I've done both self study and school in that order. Exposure is the problem in self study. You need some way of giving yourself a balanced representation of ideas. You may do well to pick a syllabus from s strong Uni and follow it right through .

The other thing of course is someone to call bullshit on you... Phil is a great subject with which to convince yourself that you are a genius . Especially when the people you talk to about it (friends et al) are in awe of your expositions since it's hardly common parlance . Keeping the narcissist in check is difficult for some.
