I've been doing this for a while. Over the years, this is the recipe that makes the most sense to me:

* be good at what you do -- there is no replacement for true competence in the computing industry;

* have fun -- together with being good, having fun makes you able to gracefully handle the work when things get challenging;

* burning bridges is a form of suicide -- there is no room for arrogance in this industry, it is a small world;

* working smart is as important as working hard -- burnout is real and life is short;
