Third: learn how to do your own data analysis. Know statistics well. Know at least some basic programming/scripting in Python, R, Matlab, etc. This will be of immense value in helping you get your research done efficiently and correctly, without needing to rely on other people's code (and time and commitment). This will become more important as our field becomes more data driven.
