Learn how to do. Learn how to produce, create, and use.

Technically, you want source control, coding. databases. data manipulation, scripting languages. Build a complete tool and process chain.

Write research and grant proposals. Publish results.

Establish your own self management regime. Find tools to help with that.

And of course, networking. That's probably the most important. Establish your network at school for students and professors. Start making industry connections. Professional groups.

School teaches you that it's all about how smart you are, how much you know, and how well you analyze. Those are all just means to production, and not really that most important. Target your efforts at being able to do, not being able to think about doing.
