You don’t need the perfect choice. You need a decent one you’ll actually follow through on.

How good a plan looks on paper counts for nothing if you abandon it in week three. The best revision timetable, training schedule or budget is not the optimal one. It is the one that survives contact with a bad Thursday, and that is usually the smaller, duller version. Follow-through decides almost everything and gets planned for least.

Take whatever you are designing and cut it back until you are sure you could do it on your worst week. Three sessions you keep beat six you quit. Add more once the habit is holding on its own.
