Direction is worth more than endless theoretical optimization.

Motion in a decent direction generates information, momentum, and compounding that theory cannot. Optimization on paper has no such feedback loop, and past a point it produces only the feeling of progress. Having a direction is worth more than having the best possible direction.

If you have been planning for a while without moving, take the most reasonable option available and start this week. Let the real world correct your plan rather than trying to perfect it first. You will discover in a month what months of theorizing would not have revealed.
