1. Don't hesitate to move locations if that can improve your career or other prospects. This gets progressively harder to do later in life. 2. Get to know people who are 5 and 10 years ahead of you in your career track. This will push you out of your bubble of same age peers. 3. There's a high likelihood that you're wrong about many things about the world in your 20's. The effect of cognitive biases (read up on them) is also non-negligible at this age. So make sure you have a feedback mechanism to validate whatever it is that you think are learning. Otherwise it's possible to be wrong about things for years without realizing it. 4. Learn at least one hard skill that can be measured objectively in some way (if you haven't already). It could be programming, maths, music, sports etc. Once you know what it feels like to genuinely learn something, you're less likely to fool yourself when learning other things later in life. 5. Develop friendships and other relationships if you find people you gel with. 6. Don't get too out of whack, health wise. Try a bunch of physical activities until you find one you enjoy doing on a regular basis. 7. 20s are a time when you are at the bottom of the power hierarchy in the corporate world and probably socially and politically as well. So beware of anti-authority, outsider-types figures who'll use this resentment to sell you simplistic solutions to everything. At the same time, keep in mind that power corrupts. Chesterton's fence and all that.
