Debugging some SQL code I wrote 4 years ago. As an old(er) programmer, I'm in that stage where I can't believe I wrote something that good.

A programmer at various ages:

15: I write awesome stuff!

25: I can't believe I used to write such bad code. NOW I'm the best!

35: I was such an idiot when I was younger! I'm never going to be a great coder, but I'm decent now.

45: I'm better than I thought I was. My experience has allowed me to write some cool code using techniques and concepts from other areas of my life.

50: I can't believe I used to write code that good. I can't believe I built some of the stuff I have.

I can't speak to how my future self will feel, but damn. I feel very old today.
