Anne,
You have already made one life changing decision in giving up drink. If you can succeed with that I reckon you can succeed with anything else you put your mind to.
I believe that in oder for us to grow and improve we need a succession of challenges to give our lives real meaning. I have decided to enrol in the UK's Open University to stretch my mind and get myself the university degree I reckon I am capable of. The thought of the work ahead, the study, the exams and the pressure from tutors is tremendously exciting, as though a whole new world is opening up to me.
Whatever it is that you want to do, whatever it is that you want to be, get out there and go for it.
All the best
Michael
