I had very little to zero self confidence since I was 13, but that is starting to change. I thought very little about myself and my abilities. I thought seriously I was ugly and fat, this is from a guy whom many say is quite cute or handsome and who weighed no more than 80 kgs (177 lbs) on a 173cm (5'8") frame. It was a shock and revelation when my driving instructor told me that a female student of my university he was teaching before me, was interested in me, she was not bad looking either.
I thought especially after failing TAFE first time around and when I was finding it very hard to find work after completing a Certificate IV in Accounting, that would muddle through life the best I could. I kind of thought even in the later years of High School I would have a middle income job, maybe an university education and be single for the rest of his life.
My total lack of confidence meant that I did not bother to socialise with fellow students on campus last semester, because I thought I was beneath them. Now things are starting to become different, I have some confidence in my talents and where I am headed in life.
