Interesting career ladder example. I especially like the various dimensions they focus on.

Lots of good insight for a long career as a programmer. Definitely a few things I live by and a few... I tend to loose sight of. More progress to be made.

About growth again, definitely from the point of view of the mentee though. This looks like a nice and lean framework to figure out where you are and where you want to go.

Lots of nice advices, both for mentors and mentees. This is definitely hard work but it's worth it for people to grow.
