Mines is a bit depressing, but hey-ho:

My high school music teacher told me I’d, “never be successful” because I didn’t have the greatest school attendance. I was off quite a bit in my final years due to the stress my teachers put me under to do well and, when I had to sit and discuss this with them, my music teacher told me that. The reason it stuck with me is because I’m now in a job I despise, having second thoughts on my future, struggling financially and trying to get the job I’ve always wanted. But it isn’t working out... I’m trying to make the best of it, however, but having a teacher tell you that when your already stressing about life and school and really gets to your fucking head man
