Nothing like the sweet moment of realization that the code you're cursing was written by your past self. That special feeling when you open a project after a break and wonder what sleep-deprived maniac wrote those incomprehensible functions... only to check git blame and find your own name. The circle of developer life: write code, forget code, hate code, realize it was you all along. Future you is always judging present you, and they're not impressed.
