I experience more like this: Have a great idea, and the more I try to write it down and articulate it, either the idea has a major flaw I did not already see, I realize its already been built and its called something else, or the idea is generally useless or unprofitable.
Add some ADD in there, and lots of "ideas" a day, and I'd say it can get fairly distracting...
Rather than storming new ideas, I find it particularly hard to stick on a single idea.
So many people have lots of "open" ideas that never just get executed properly
