If it’s the second: go with the last idea you rejected. Give up on perfect and see where a less-than-perfect idea takes you. Would you do a perfect painting from a perfect idea first time anyway?
If it’s the third: put several in a hat and pick one. They’re all equally valid, and it matters more that you get started and persist.
