Ideas are not worth very much, and many try to focus on world-changing ideas, which is the wrong approach. I sit on two or three profitable ideas at any time, there's just not enough hours in a day to dedicate serious effort to any.
Effort trumps everything. The difference between a dumb idea and a multi-million dollar business is how much effort you put in.
So effectively the problem most people have (including me) is finding an idea you will keep believing in even after the hype and excitement has faded down, and the only thing standing in front of you is the mountain you still have to climb.
For me it's actually that I have too many ideas and none of them are great. What makes ideas great I think is having the right people to try things out with -- hence this tool.
I have the same issue. I have too many ideas with very limited amount of time to work on them. When I meet people, I want to share my ideas and get feedback about what they would find interesting, use, pay for, etc.
I'm building a platform to do this, so I can share my ideas.
