Some moments it feels longer, other moments it feels like it's flown by; you can't believe you've done it all that time... Overall, you have a strong sense for the full spectrum that you've sort of traveled.
I admit I can't shake the idea that there is virtue in suffering, that there is a sort of psychic economy, whereby if you embrace success, happiness and comfort, these things have to be paid for.
Always admit when you're wrong. You'll save thousands in therapy... and a few friendships too.
