Ask HN: Techniques for remembering to find the 15 minute solution

I'm constantly wishing that I would do a better job at finding the 15 minute solutions to problems instead of the 2 hour to 2 day solutions to problems.

By "15 minute solution" I mean if you had 15 minutes, how would you solve this problem? The idea being that most of your solutions get redone, thrown away, not used, or don't solve the problem anyways so you might as well just do the quick solution up front to save everyone time.

The only method I have right now for reminding myself to find the 15 minute solution is the Pomodoro Technique and a daily todo list with time deadlines every day.

What's your way of reminding yourself to find the quickest solution to a problem, not the best?
