I you don't even know that you have made one, then you probably haven't made one!
there is something called incidental change, or change which you dont know but finally come to realization and know what you have done in later date.
If thats what you are talking about? Then:
I have decreased my smoking.
started working out.
lost my girlfriend over a white douche and felt proud of it...for some reason. :S
Attempted to gain G1...abhi tak nahee lia :(
started my game development project and finished the storyline with few sketches
thats pretty much it for now I guess.
