Math is really incredible. I started to migrate towards math, physics in first yr of college and somehow managed to get an engineering degree. It's amazing how math explains the physical universe. I forced myself to understand calculus. I passed differential equations but I couldn't tell you what it is off the top of my head. I made a mistake and went to PSU - much too large for me and I encountered severe personal/mood problems. I wish I had gone to a smaller college but it doesn't matter know since I'm on disability. I've found that I don't have an engineering work personality - sweating the small things and over-analyzing is really poor for my mental health. My head needs to be freed up most of the time to stay healthy.
