What if you aren't a finisher? How can you become one?
I wish I were as good at taking this advice as at giving it.
1. Lose the fear. (This is the root cause of all the other stuff.) Or, more
accurately, experience it but don't give in to it.
2. Timebox the work (as reasonably as one can) or limit "one more feature".
3. Fail fast, gracefully, and quietly. Learn when to *not* finish.
(You shouldn't be finishing *everything* you start. The problem is if
you finish *nothing*.)
4. Succeed decisively but simply (not ornately; don't aim for perfection).
