I found this inspiring bit of advice underneath a Bearmageddon comic a few days ago:
One thing about success is you don’t get to choose if or when it will happen. You don’t get to choose what project it happens with. Other people choose it. When the internet went wild for Axe Cop, they chose for me my success, my path and my future. I did not set out to be the Axe Cop guy.
While he’s talking about art, the point applies to nearly every field. All you have control over is whether or not you enjoy what you’re doing.
