I have a list of ideas and I rank the ideas by how much I like them. So the top idea in the list is the idea that I'm most passionate about.
Then from the top of the list I think about these factors:
1) How big is this idea, can I achieve it with the time/resources I have budgeted for? Resources can be funding, helpers, co-founders, technology, etc
2) What is the market size of the idea? Can my team support the overall vision?
3) Who are the competitors? Or is there a competitor? If there is a competitor, can I compete with the available resource/time that I have?
Start from the top idea and if any of the questions raises a red flag, move on to the next idea. You don't have to use the 3 questions I provided above, just add your own questions but the methodology is the same.
