I'm a BIG fan of basing your learning on your passions. My personal opinion is that true learning only takes place when we're passionate about the topic. So I was excited to find a new blog written by 21 (!) year-old Amir Ahmad called Passion-based Learning.
Right out of the gate he has two great pieces, one on 7 Easy, Powerful Steps to Create a Personal Learning Environment (which, of course, fits right in with my own interest in this), as well The Ultimate List of 50 Kick-Ass Blogs to Boost Your Learning Experience. Amir's just getting started, but he's already doing some great stuff. I also love that he's so smart already--he completely gets the need to be self-directed in your personal and professional development. And they say Gen Y is lazy!
