In the time of Aristotle there was a philosopher named Zeno of Elea who hypothesized several paradoxes including his famous, Dichotomy Paradox. The basic principle was that in order to travel from any point A to any point B, you first had to travel half way there, which would take a certain amount of time. Then you would have to travel halfway between that point and point B, or a quarter of the way there, and that would take a certain amount of time and this would continue to an infinite number of half ways and an infinite amount of time so essentially this would render motion of any sort, impossible, thus the paradox. If that explanation was really confusing for you, this video might help make more visual sense.
Make more sense now? Good. This is a perfect image for thinking about micro goals. Whether the project you are tackling is very complex or very simple, breaking it down into it's most bite sized chunks is absolutely essential to success. When you break it down a number of things become possible.
First, this helps in Creating The Manual of You because if you can identify the individual steps required to complete the task, then you can start to optimize, automate, and outsource them. It also gets over the psychological barrier that typically stops people from taking action since this once huge problem is now just a matter several baby steps. This way you can tell yourself, JUST GET STARTED and then every step of the way you are achieving little successes that motivate you and focus you so that you be even more confidant and effective.
So next time you get stuck in analysis paralysis or you're stressed out about a looming task or project, focus your efforts on breaking it down into micro goals and remember Zeno and how infinity is not really infinity.
