Sometimes it seems difficult to find what action you should take or the necessary action seems overwhelming. This is common and that's where the idea of chunking can help you out. This idea is that if you break something down into small enough pieces you can accomplish almost anything. There is the joke about how do you eat an elephant? One bite at a time.
Now with this said, I think it is also important to keep a sharp eye on your goal and use any small action to help you to generate momentum. It is possible that you will start taking small actions and then be satisfied with the small actions and give up on your goal. In reality, it is not going to be all small steps that will allow you to achieve some of your goals. At some point, you will be required to take some big steps and actions, and it is OK if you aren't ready or able to take them right now, though they must be taken sometime.
I like to use weight loss analogies, so here's another one. Let's say you want to lose weight and you realize eating more vegetable and exercising are some of the key actions to being healthy, it is just too hard for you. A small action you decide that you are able to take is to switch from regular cola to diet cola. This is a great first step and if you stop there, I hope you don't expect to get much of a result. Take this small step and then take another small step by maybe putting one piece of fruit in your bag each morning and eating it as an afternoon snack. Then maybe add a salad to your lunch or dinner each day.
The key above is to take the first small step and celebrate this success and then to take another step that is maybe just a little bit larger. Use the momentum of that first step to take another step and another. If at some point you fall down, that's great. Pick yourself up and take another small step, whatever it is. It is by taking many small steps that anyone who has climbed Mount Everest has gotten there.
What action are you going to take today to achieve one of your goals?
