GS, it sounds like you really climbed the ladder there. I have done some bar work, but not at a high level like that in somewhere posh like Oxford! I really enjoyed the social aspect too, and found it enjoyable. Worked tills in a hardware chain for almost 3 years too while I was doing A Levels.
But I had always wanted to do what I'm doing now, eventually. SO here I am!
I understand that I am in a fortunate position, being able to attend uni, live independently with my partner and enjoy a reasonable standard of living for our income. I am working now too, so that's a help. But it's not always that easy, and it's amazing that despite the emphasis placed on education, there is little incentive to engage in it. My course has been such hard work, and I have been on the verge of quitting so often (as have most of the class!) but I have learnt so much, and it's set me up in a career i will love forever.
I am not so concerned about the money I will earn, as long as we get by, I just want to be proud of what I do and enjoy it too.
