I usually think about: Friends Relationships/women Family Better ways to spend my time Things I don't like about my life and how I intend to change them But at times when i've been lonely/deep in thought i've worried about: My future What makes people like me? Where do I want to end up/what should my ambition be? and why have I not been chasing it sooner? I often beat myself up (not literally) for spending so much time online over the past few years when I could have been doing much more rewarding and productive things (my personal opinion and is aimed at myself and no-one else). But all in all I tend to follow my motto of positive thinking leads to progression. (and for the record my life has been far from perfect, i'm currently unemployed after graduating, had a mother and brother who both were manic depressants and alcoholics, i'm from a split family, Dad left when I was 3, I moved 250 miles away from friends and family for the sake of my mothers health. I just choose to be a positive person, what doesn't kill you makes you stronger. I learn from my experiences and they make me a stronger person.)
