>>They're not loyal to you, so why should you be loyal to them?

This always comes up in such discussions, but who exactly is They here. Company isn't a conscious entity, its the people. And those people are likely saying the same things about They as you/we are.

The real deal here is we have 100% ownership of any situation in life, and we are not loyal to ourselves, given this obvious fact.

If you have an opportunity significantly better than your current job, you must make the jump. But people often change jobs for petty reasons, which don't give anything much in the longer run. On the other hand, your perfectly good growth at your current place gets interrupted. Heck stability in itself is worth a lot. It helps one focus on relationships, fitness/health, consistent savings and investments, and debt raising for some investments(like buying homes etc).

People keep talking about compounding growth, and yet keep changing their process. In fact its sticking to one thing and doing it right is what causes compounding growth.

I'm not even sure I even understand what you're saying here. It seems kinda all over the place.

"This always comes up" -- really? You always hear quotes from 60+ year old people? Somehow I doubt that.

This came from someone with a lifetime's worth of experience from one company. Naturally he might have had different experiences with a different company, but on the other hand, he at least knew people from all over.

My impression from reading various accounts from people with long careers in tech is that the stuff that compounds also transfers. You don't take the obsolete frameworks and libraries with you (for example), but you take what you learned about frameworks and libraries.
