I feel embarrassed when I read my old code. Gee, did I really spend THAT much time thinking about the solution? I thought I was such a hot shot when I wrote this…
It’s good to be embarrassed. You weren’t terrible then, and you’re much better now.
Before my first conference talk, I was feeling particularly nervous. (I hadn’t been so nervous in years!) To calm myself down, I admitted this first talk will be the worst talk ever. I have to start somewhere, but every talk from now on will be even better.
When you look back on your first conference talk, you will be embarrassed. Gee, did I really say so many ums, did I really have to freak out?
And that’s fine. You’re so much better now.
