Corporate America doesn’t care how smart you are. A wise man once told me your first degree might get you in the door, but after that it’s all about what you do in the workplace. And the best thing you can do is network with the right people, maintain upward momentum, and if at all possible, avoid doing any real work. Unfortunately, there’s little glory or reward for the technical experts who really make things work and bring in the dollars that the CEOs brag about on their new yachts.
You should’ve found your soul mate already. The dating scene changes dramatically after college; no longer are you surrounded by people your age and intelligence. People are tougher to find, much less idealistic, and many are already married or in long term relationships.
You never stop learning. The technical world moves so fast that almost anything practical you learned is outdated before the ink is dry on your diploma. Many work in fields only loosely-coupled to their studies, and being successful often means learning a good bit about related disciplines. One caveat is to avoid letting yourself become spread too thin; another piece of good advice I’ve heard is to be knowledgeable about all areas and an expert in one.
