I haven't used my degree directly but I have used elements of it, but more importantly I have used what I learnt during my degree - I gained confidence and courage, improved skills I already had such as public speaking and cooking, learnt to budget, met wonderful people who are still in my life, experienced and learnt more about other cultures than I could have learnt from books/tv/internet, reactivated one person created many friends of the church particularly in the muslim community. I have friends around the world who know who I am and what I stand for. Had I not gone to uni I wouldn't have worked at summer camps were I directly affected the lives of of serveral hundred children and which got me back into Guiding were I have impacted many more children and adults including bringing one person into the church. So I while I may not actually be using my degree I don't feel that it was wasted.
PS thanks for helping me to see what I gained from my time at uni.
