Ideas are overrated
It’s easy to come up with an idea and expect someone else to do it. What is important is the execution of that idea. It doesn’t even have to be the whole thing. Just do one part of it. My personal goal now is whenever I have an idea I must draw it out and see if it is worth exploring.
If you put it on paper, then you can start refining. Otherwise, the idea is perfect and “just works” in your mind.
