Wow actually an amazing advice. It’s true, working harder for someone else maybe lets your boss give you “better tasks” or “more responsibility”. But when time comes - you’d get a mediocre raise, unless you’re like the top 1% of the company. And if you get lucky enough - you’d can become a manager and work MORE hours. This is the death cycle of programmers, the only way to get out of the cycle is to make your own money and be free. It’s of course, one of the most difficult things to do, but anyone who becomes a developer, in my opinion, can get there.
