I had a busted lip that would not stop bleeding. I had been playing too much for far too long and my lower lip final said that is it I quite and it split right inthe middle top to bottom. I played the concert that night constantly going through paper towels and hankies. It took like two weeks to heal up enough that you could not tell it was injured and another two weeks before I could play onit with out pain. Total time to heal from the time it happened until I was back at 100% was like 6 weeks. It sucked. In fact not only was I playing way too much but I was tutoring other students to replace me so that wne I left they could step in to my spot. So on top of regular practice and playing I was tutoring 2-3 hours out of the day and I was also getting ready for try outs at my new school even though I had already won a partial scholarship I wanted to be at my best so I was putting in way to much practice time. It was just too much. If you want scarry I was once forced to fly hung over and with out much sleep. I had been parting for two solid days then I went to bed and slept about 3-4 hours. My phone rang and after three other guys calling in sick it was my time to make a run to deliver and pick up mail for Fed-Ex. I was still in college at the time and the guy running the show was also the main flight instructor at the college. I told him I was not scheduled to fly for two more day's and was hungover and tired. He told me to get my but out tot ht air port. He had two pot's of coffee already made just how I liked it and told me to drink them fast because I did not have time to waste. When I asked about flying in my condition he said to me "Welcome to commerical aviation!!!" he walked out the room laughing. That day alone I stoped at about 10 diferent small airports to pick up the mail and drop it all off at their processing center. The fog was so thick I could have sliced it into cake and served it with tea or coffee! The laser's where reading 0/0 so even the duck's were not flying that day......That should scare everyone!!! No I have never done anything that stupid before or since. I felt pressured because my college proffessor was also my boss and I did not feel like I could say no! I made sure to avoid putting myself in that postion ever again!
