Yeah, I don’t know how much I have to add to this one. Though there’s a related Jim Rohn quote that I like:
“Work hard at your job and you can make a living. Work hard on yourself and you can make a fortune”
The overall gist of both of these is an insight that I wish I’d internalized sooner. “Just” doing your job, “just” execution is good. It’s necessary but it’s not sufficient – at least not for those who want a “rich” life (for whatever “rich” means for you)
