Success Amnesia (shervster.tumblr.com)

We live because we enjoy living, everyday, every hour and every second, not limited by the day of success, nor shall we be burdened by the occurrence of failure. We work because we enjoy doing so; we enjoy to know the fact that we are spending our time meaningfully. Success serves the role of imforming us that we are heading to the correct direction, and failure just tells us to change our direction. That's it. Nothing much.

Isn't it an optimization problem?

Yeah, that works very well for me. No worries, very much happiness plus while for reflection on fail. I like it. :)
