Personally
>Start working out some more
Already work out but i've got to work out more since i'm unhappy with myself.
>watch my diet and what i eat
Watch what i eat and when i eat it, want to lower my bodyfat percentage, right now i'm around 17%.
>do more for uni and try to get motivated
Will do a different study in a different city next year but i will finish this year irregardless of that, will try to do my best and pass my classes.
>be more outgoing
Feel like i've been in my room too much instead of going out or doing some stuff besides studying or vidya. Will go out more often and try to have more fun.

This is basically it for me familia. I think i can get myself to actually make these resolutions come true. Let's hope i'll have enough discipline.
