I've never been able to focus adequately enough to do well in school. I'm finished with it now but I found my school years to be disapointing because of the lower grades which pretty much shut out any chance of doing undergraduate research or a chance at grad school -- ever. Students rolled their eyes when I asked a question, professors sighed and shuffled their papers at me when it was time to return exams. I always felt like I was being judged and looked down on during school years. One possible explanation that I can't shake is that I never belonged in college or grad school anyways. At least it's over now. Nowadays I get to look forward to being judged by my colleagues. Until I retire or die.
