Max, you're still spinning your wheels and haven't crossed the start line.
Action is needed, not excuses. So far, you really have no personal cost associated with your lack of action. So, here's the plan. To make the cost of excuse-making high, and hopefully spur you to action, each time you make an excuse, or point out some new facet to this whole thing that worries you, administer the Stijn Solution™ to yourself. A punch in the nuts. You'll either (a) get cracking on your part of the challenge, (2) grow to like punches to the nuts, or (iii) enter the priesthood. Good luck, step away from PPOT, and get busy.
