There is an often repeated saying "Insanity is doing the same thing over and over again and expecting different results."  It appears the best evidence is that this was first said by Rita Mae Brown.

You might want to check yourselves to make sure that you are open to doing new things in order to get different results. 

This is similar to the often quotes saying that Thomas Edison failed 1,000, or 5,000, or 10,000 times before finding a combination for the light bulb that worked.  He is reported to have said something like "I have not failed 1,000 times, instead I have found 1,000 ways that will not make a light bulb."

So persistence does not have to mean that you keep hitting your head against the wall.  You might want to evaluate how what you are doing is helping you achieve your goals.  Do you have the belief, feeling or evidence to show that what you are doing is getting you closer to your goal?  If you do than, keep going and be persistent.  If not, then make some adjustment, small or big.

When you are trying to form a new habit and develop your mind it takes time.  Unlike trying a new design for a light bulb, developing your mind requires patience   Would you go to the gym one time, then jump on the scale and if you didn't see results, stop going to the gym, or radically change your workout?  You have to allow time for your actions to influence your mind.  At a minimum, I would expect 1 month to be enough time to see results if you are taking regular actions 3-5 days per week.

My advice then is to choose your goal, take some action, and then keep taking action at least 3-5 days per week and do that for 4 weeks.  After 4 weeks if you do not have any evidence, feeling or belief that your actions are producing results, then change your actions and try again.
Everybody gets tired.  It doesn't matter how smart, motivated, successful or positive a person you are.  This is a fact that we must accept and then figure out how do we deal with it.

There are different types of tired.  There is mentally tired and there is physically exhausted.  For true physical exhaustion, there is not much else that we can do except rest.  All people require sleep.  It is as important as eating and drinking.  How much rest is required is debatable.

It is rumored that some high achievers like Michelangelo and Thomas Edison never slept more than 4 hours.  Maybe employing some sort of polyphasic sleep pattern.   I used this method in college to have more study time.  I find that I can sleep maybe 2 hours less in the evening if I take a 30 minute nap sometime during the day.

Here we are not talking about physical exhaustion, instead about mental exhaustion.  When we just no longer have the motivation or desire to continue with our tasks at hand.  We know that we are mentally exhausted if a different activity instantly energizes us.  An example might be that if you are resisting doing something that will help you achieve one of your goals, and then a friend calls up and invites you to go play.  If it is a person that we have romantic interest in asking us for a date, then the level energy can instantly change.

So, how can we develop this level of enthusiasm for the things we should do instead of just having it for the things we like to do?  Just asking the question, leads to a possible idea.  How can we learn to like doing the things we should do?

Having clear, believable, passionate goals will make working towards them something that we like to do.  We generally lose interest in our actions when one of these three things are missing.  If your goal is "How can I be a better person?"  This goal is unclear.  If your goal is "I will make US$50,000,000 by the end of this month."  Unless you already make this type of money, this goal is not believable.

Check that you have clear, believable goals and that you are passionate about them.  Now even with this, there will still be times when you are mentally exhausted or can't seem to take action towards your goal.  The first advice is do something anyway.  Don't let your feelings rule your life.  Put your mind in control.  Force yourself to take any small step, no matter how small.

Even with this advice to take action when you don't want to, you have the option to rest.  Just like physical rest, we also need mental rest.  It is OK to take a break.  You can even decide to have a mental break every day.  You can take 1 or 2 hours everyday, if you so choose, to do nothing towards your goals.  You can watch TV, read comics, play games, surf the web, or do anything that many people might consider a waste of time.  I consider this letting yourself rest mentally.

As we develop new habits, the amount of rest we want and require may decrease, so you can adjust this amount of rest time as it suits you.  The point is that it is perfectly OK, to take a break, just don't make it what you do most of the time.  Most of your time should be taking actions toward achieving your goals.  If you are not yet spending most of your time trying to achieve your goals then review your goals and make them clear, believable and something that you are passionate about.
The only people who fail are those that stop trying.

As I write that, my mind is wandering about finding a substitute for the word "try" because I have heard several success coaches who say something like "There is no try, only do or don't do."  Hmm, sort of simplistic and not necessarily helpful advice.  I get that their intention is to encourage a positive mindset so that we tell ourselves that we will do something and only be happy if we actually do it instead of being happy with the fact that we just "tried".  I'm not so strict, I think it is perfectly fine for us to "try".

Anyway, the point is that as long as we haven't given up and quit on achieving whatever is our goal, then we haven't failed.  As long as we are alive, we still have the chance to pick ourselves up and work again towards any goal.  Do you want to make more money, have a better marriage, be happier, or healthier?  Have you tried to achieve any of these goals in the past?  Maybe you have read books, attended seminars, made goals to achieve them, even written down goals and possibly even had success and then fallen back down.  That's all great.

Again, if you are alive enough to read this blog, then you have the ability to try again.  Take another step.  Learn something more about what you are trying to achieve.   Ask the question "How...?"  The technique of asking "How..." is a great way to get the most powerful tool that we all possess, our mind, to work for us.  Ask your mind a question like "How can I make more money?", "How can I get in better shape?", "How can I have a better marriage?" "How can I be happy?" "How can I learn to set goals?"

Asking "How...?" gets our mind working on our side to help us achieve our goals.  Ask the question over and over in whatever tone of voice is comfortable to you.  You can ask yourself silently, just in your mind.  You can say it out loud.  You can say it softly or scream at yourself.  There are no rules here, just ask the question to get your mind working for you.

BTW, you can also get the minds of other people working for you by asking the same questions to them.  You may be surprised who was a good dea that can help you achieve your goal.

Be persistent in achieving your goals and keep asking "How.." questions.
