I’m going to slightly disagree with some of the other answers here, since I actually did travel and socialize a fair amount myself during the university years.

I’m going to slightly disagree with some of the other answers here, since I actually did travel and socialize a fair amount myself during the university years. It was fun, but if I could give my younger self advice, it would be: your financial life is starting now, not in 10 years. Travelling is interesting but humans are similar everywhere and people have lived happy lives for thousands of years without yearly international travel. In terms of career advice: interview your employers just as selectively as they interview you. Take your time making a choice. Don’t hesitate to leave for better opportunities, even if you’ve only worked somewhere a short while. Do side projects. Try to charge by value, not by the hour; get some economic multiplier.
