Genius may conceive, but patient labor must consummate.

The idea is the cheap part. Conception happens in an afternoon and feels like the achievement, which is why so many good ideas are described enthusiastically and never built. Everything after that is unglamorous: the second draft, the tedious middle, the corrections nobody will notice. That is where the thing actually comes into existence, and it asks a different temperament than the one that thought of it.

Take the idea you have been most excited about and give it two hours of dull work this week. Not planning, not talking about it, the actual grinding part. Repeat that enough times and you will have made something rather than imagined it.
