I have an obsession with learning and being able to recall everything that I have learned. I feel somewhat panicked when faced with the notion of having forgotten things that I spent time absorbing. This is actually the main reason I have a website.
My goal with the study portion of my site is to eventually have tutorials in my own words on every single subject that I find interesting (or at least those that are technically difficult) so that if I ever feel fuzzy on one of them I can refer back to my own stuff. This way, I can learn via various methods, absorb it, then regurgitate it in my own way for later use. This project is my main long-term, tech-oriented goal.
