I've enjoyed the ride and look forward to see what the next 20 years will bring. (I'm not retiring any time soon).
In retrospective, I am grateful for discovering web development. I really like it. A "regret" has been not focusing on a single thing and specializing in it. It's fun to try new things, but IMHO it closes more doors than it opens in the long run.
Let the rollercoaster ride of a tech career continue.
