What do you do if you have no idea what to do? I mean, what if your mind is a complete blank? You try to ask yourself questions, like "What do I want?", or "How can I improve?" and all you hear is the echo of the empty chamber between your two ears.
I guess some people would suggest to "Just Do It" anyway. Just do something. Anything. Get up and go outside and walk around the block. Get up. Get up. I think that sitting in from of the television or randomly surfing the web would not qualify as "doing it".
Give it a chance to try and break out of whatever it is you are doing now. It's very possible that by doing this nothing will happen. You will return from your activity still with no idea what to do. That's OK, at least you got up and did something, no matter how small. Reward yourself for this little success.
A journey of a thousand miles starts with one step. This activity you just took may or not be one of those steps, but remember if you are looking at the thousand miles, you won't even be able to see each of the steps and when you look at one of the steps it may seem unbelievable that such a small thing could ever add up to a thousand miles. Have a clear understanding that those small steps do indeed add up to thousands of miles.
