Being an anonymous cog in the machine is not a good feeling, but unless you make a unique contribution to society, do you really deserve anything more?
I want to make such a contribution, but I have yet to find one that I would enjoy making and other people than me would appreciate.
One thing that annoys me is that you can't test the waters for an idea by explaining it to people. You have to implement several ideas and see which ones stick. That's way too much wasted time and effort.
