At my age (not brand new) I have seen some dramatic career arcs amongst friends, clients, and former colleagues. I LOVE the long perspective, because it shows so many reasons for hope.
1. There are highs and lows in EVERY creative career. Even the most gifted artists do some rotten work, in an effort to get to the great result.
2. It is never too late. We worship youth, but youth is fleeting. Good work is forever.
3. Amazing achievements happen. Like Rick's bar in Casablanca, success might walk into your gin joint. Be ready.
