self realization -- about many things

i guess today was a day  for self realizations.. i had a discussion with a friend which was mainly dominated by me telling her my 'biography' :) .i was telling the things i remember from my childhood till date, about all the people i met, the effort i have put in to make my relationships work.and when i say relationships, it means each and every relationship i had ,with my parents,my friends etc..i have realized i have put in a lot . i would have been in a far far better position i my life i would have just concentrated on my own life then on working on my relationships..
anyways i have learned the hard way.
