College Advice

For those of you who have actually worked in the field, what kind of suggestions or advice could you give to a college freshman going into Computer Science? Things to do in spare time, what's important to learn and what isn't, fields to look into, etc etc, whatever you find relevant.

(P.S. My college teaches C, I've been programming since high school, and I have been reading SICP)

If you aren't already spending your free time writing code, GTFO of software engineering.  You will be hated as dead weight and will never progress, since you will be always be bumped by those who have a drive for software and didn't just get into the industry because it "looked good".

Do get into sysadmin, DBA, etc, if you like being meticulous and can be thorough, responsible, and continually self-learning at a reasonable pace.  Those are things that can be learned and don't involve a lust for creativity.
