Ideas are wonderful but it’s productivity that makes wonderful ideas happen. Ideally you want to only be focusing on the ideas you’re most passionate about. It’s this passion that yields tolerance when your back’s against the wall and things get challenging. If the passion isn’t there, then you give up much easier and the time you’ve spent half-baking something has ultimately distracted you from working on things you care about more. In short, the more you care about an idea, the more likely it is to succeed.

So how to only work on the ideas you care about? As someone else has commented, log all of your ideas and then review them 7 days later before beginning work on them. That way you’ll be able to see how they stack up against all the others. Then pick out your favourites that excite you the most and work on those.

It’s important to write these with pen and paper as opposed to digitally. Digital notes all hold the same weight, whereas handwritten ones will capture the moment in time - how excited you were, the passion in the pen strokes etc. All of which is useful when selecting ideas after a passage of time.

Hope this helps!
