Idea praxis:

There are many ways ...

- make things for yourself & solve your own problems

- take notes in notebook

- observe from nature

- don't be obstinate (in-flexible)

- revise your ideas & filter

- listen to your users

The thing is some ideas are crap. Others maybe ok. But it's what you do with the idea that matters. Turn the idea to a demo. Release the demo and see how many users pick it up. Re-visit your old ideas

It's how quickly you can turn idea to demo. Unleash your ideas in the form of a demo on your users. You'll find out quickly if they are crap or not.
