The goal you have chosen may feel like it is unattainable or far away (for example, maybe it will take a few years to accomplish, or you have no idea how to actually accomplish it). However, you may be able to think of some things (subgoals) you can do now which seem like they may be beneficial to your main goal. For example, if your goal is to start a business, a good first step might be to figure out what a good business idea might be, to do research about your potential business, or to start working on your business plan.
The exercise to focus on here is finding something that contributes to your main goal that seems attainable. Once you have found this goal, write it down on its own piece of paper and keep it with you at all times until it is accomplished. Every day until you are finished with this guide (preferably you should choose to make this a lifelong practice), you should keep this paper with you. If you find that you have accomplished your goal before the end of this guide, you should immediately consider other things you can do now which may seem like they are beneficial towards you main goal. If you have already completed your main goal, choose something else to improve upon from the list you made in exercise 1.
