A couple of years ago the media were calling for Roger Federer to retire. He was on an bad run of and slipping down the rankings. When asked in an interview about retiring he said this:

"Sometimes you're just happy playing. Some people, some media, unfortunately, don't understand that it's okay just to play tennis and enjoy it. They always think you have to win everything, it always needs to be a success story, and if it's not, obviously, what is the point? Maybe you have to go back and think, Why have I started playing tennis? Because I just like it. It's actually sort of a dream hobby that became somewhat of a job. Some people just don't get that, ever."

This summarises me my mindset. Replace the words "play tennis" with "make stuff" and reread Federer's answer.
