Low intelligence? You have a degree, Thats HUGE! Doesn't matter what grade is attached to it unless if you want to work in canary walf or wall street. I'm a 23 year old stammerer and I've learnt to live with it, it's not easy all of the time, but now it's part of me, I'm good with that, took a lot of time but it's all good. I think as a stammerers (if that's a word) we have to work extra hard working at our confidence, took me years and I'm still not 100%.
