Start. Do it. Go do whatever it is that you have been wanting to do. Do not fall into that trap where you say that you are a perfectionist therefore you need to get every bit of your plan in order before you actually start. If you are a perfectionist, I know this is scary indeed. But always bear in mind, those who are now successful, the people that you admire from afar, want to be like someday, most if not all did not know for sure if the path they had taken will lead them to where they are now today. Stop waiting for everything to be aligned, just start from wherever you are right now.
