The advice that I would give to myself in my early 20s is (1) nobody cares about your career except you: people come and go, change companies and have their own careers; (2) the only way to move up the ranks is by shifting between companies and getting multiple competing offers; this applies even to outstanding devs; so you are expected to move every 3-4 years if you don't want to get stuck at your entry level pay.
