Same, but part of that is I realized how much I didn't know about things which I was originally quite certain about. Epistemology is a field which is sadly usually confined to religious schools. It's pretty eye-opening when you start applying it to things you think you knew.

It was more than a little disturbing when I started reading the methodology sections of scientific papers that make the headlines and I realized at LEAST 90% of them were absolute bullshit.
