Semantically speaking, you can't teach yourself - only others. Teaching implies imparting knowledge or skill, or to give instruction to someone (other than yourself).
what if you have multiple personalities? would one personality be able to teach the others?

it could be done, right? might not be at the same time, but in asynchronous time?
no, i am discussing with aikiweb folks! go away! *sorry again, evil phi #999 keeps asking for things to do*
just trying to find out if there is a good chance that i can teach myself.
