Ways to celebrate living

Adult life is not simple and sweet - we do not allow it to be so. It is easy to generate dozens of reasons why something can't be done, or how my personal condition is tough, inelastic and grim. Frankly, I'm not much interested in comparing who has the life more mired in shit and despair. There's plenty of that around, no need to look far. I'd like to hear from those who've overcome adversity. Let's hear from those who've risen above mediocrity. Please tell us how / why you enjoy or celebrate life.
