Yes, that's very true. School IS the most important thing right now, but I feel like I can still focus on investments, right? I mean it's not a time consuming thing. I work 10 hrs/week during the semester and I will be interning every summer at nice pay, and 80% of everything I make will be put into an investment account.
Again, I like to browse discussion groups, my preference are the groups on Morningstar, to build real world knowledge from people who have done this and been through a few investing cycles. Those groups will lead you to good resources for further research.
