I like the humble part., surprisingly the best coders I have met are very humble. You should also mention to contribute to open source projects when they have some free time and to learn from their coding mistakes. Emphasize more the "Don't blow off your non-CS/ECE/EE classes!", this is an important point, not only because it can lower your grade, but I believe, because it makes a well rounded person. If you are well rounded, you will learn why it's not so good to be hacking away in front of a monitor for 30 hours straight (even though it's fun), and that your health, above all, is the most important thing. Also building up mental discipline is key, every project has some fun things and boring things; discipline will help them to get through the boring things so they can enjoy doing the fun things later on and finish the project, there is no point in starting something if you are not going to finish it. Just my 2 cents.
I can't agree with you more regarding self-discipline. My senior year in high school was the biggest joke: no one had to attend class, complete work, follow school rules, etc... but everyone got at least a C because teachers who cared about their students got their feelings twisted and wanted to make sure everyone graduated and the administration wanted more funding for higher graduation rates. Result: I completely slacked off and drank with my friends too much and lost all self discipline for my first year in college. I took all random classes, not even working to tick off GURs, and now I have to pick up my own pieces now that I have pulled my head together and figured out what I actually want to do with my life.
