Thanks everyone, the personal anecdotes are the fuel I need to keep me motivated. It's tough when you see lots of big news about developers at startups doing amazing things and you just think 'well, I didn't do x,y,z perfectly, so I'm not eligible for this kind of project'. I work for a fairly small company that's existed for over 10 years but is still in startup mode, probably for the wrong reasons. But it's convinced me that startups and other small outfits are definitely where I want to be. Thanks everyone!
