The secret to "Ideas are easy"

Once you get experience, you will have ideas.

Once you are present in the moment and see problems, you will have plenty of ideas.

Once you have problems, you will have ideas.

Are they good? marketable? Can you execute on them? What makes an idea good?

These are the hard questions that I struggle with because I'm interested in many things. I like puzzles. Puzzles are like mental sex.
