I think it is impossible to know who you are and what you are like as a person at 19, 20, 21 years of age and whenever someone asks what your strengths and weaknesses are I don't think a person at that age would really know the answer- at least I didn't anyway. You never really know but you never stop searching for the answers, you never stop learning or trying to understand yourself and I think a lot of pressure is put on people to make decisions about their lives without really knowing why. Trying to find your identity, in my opinion is a lifelong quest and the answers are not always definite or clear. I'm 31 and I still haven't got all the answers, I'm still soul searching.
