Most of mine come from being eternally curious about the world around me - questioning how things are done, why things are done a certain way.

Ideas tend to strike me when something happens that either makes me happy or excited (which I then want to make repeatable or shareable with the world) or when I see something that makes me sad, or angry (which I then want to make better, or eliminate or prevent).

It can be difficult to sit down with the intent to "have some ideas" which you could translate into startups.

The other thing to note - most of the ideas I come up with go into evernote - never to return. Why? Were they bad ideas, no not really, some are quite interesting. However, they aren't things that I have a strong interest in or a sustained passion for.

No matter what you do to generate your ideas - ensure that they line up with the things in life you can't do without - the things that you'd do even if it wouldn't make you any money.

Regardless of the quality of the idea - if you can't stay excited about in the face of all sorts of difficulty, adversity, and struggle - in an environment of extreme uncertainty and instability - it won't be long before you are thinking of the next idea and wishing you'd never started this one.

The best ideas in my opinion, are the ones that hide among the weeds, on the foggy edges of the thing or things your mind turns to on its own, when given the chance. Opportunities are everywhere - so look near the things that interest you most - those are the most likely to be suited to you.
