I used to create music and then upload every single idea. I never realised that until it was too late that it would be the reason no one really listened...
Writing many ideas is great, it means your creativity is on overdrive. But what could really work is collating the ideas together and combining elements in to one project :) When I set out making a game with RPG Maker, I had to discipline myself to make one project only and make it work somehow against the back drop of saturated RPG Maker releases...
I've learned more using the engine for one game then I could have by making 50 game ideas. It takes time, and surely sometimes you need to go away because you're missing that one thing , it drives you up the bend. But it's really worth hanging on to an idea then making it grow, which in turn you will also.
One thing you could try is having a listen to the GDC seminars on You-Tube. When I had nowhere to go, there was a game developer with massive experience who was there to help. Game devs from Indie and Mainstream talk to an audience about their experiences, good and bad. Really cleared some things up for me, this could help also :)
