I can give you an example of when you overstay that rule: You WILL get bored, you will lose all drive to deliver results, you'll destroy that reputation you build. You'll have a hard time finding another job because your references are no longer positive. Get out while you can. I didn't.

Started in my mid 30s. I was never good at it, but I started to enjoy it, when my knee started to act up. Doctor said it was because of an old issue from a motorcycle accident and I could either have surgery with just a 50% chance of success or drop running. As I was doing (amateurish)Triathlon training at the time, I dropped running and focused on cycling and swimming. I enjoy this very much now and even get decent progress. I'm approaching mid-40s now and I hope I can do it much longer still.

I don't know who initialyse selected the rubber duck as a symbol for that. But it can't be a coincidence that the method works even better for me while showering.

(Although with that, the energy costs might rival that of AI use)

My kids can do the same look...
