Doing it for me?

So I've been looking back at my accomplishments in life thus far, and I've noticed one commonality among everything I've ever done. It's never been about what I wanted for me, but what I wanted for the sake of someone else. Anytime I've ever been inspired to do anything or try to work towards a certain goal, it's never been for the sake of me rather it's been because I had a desire to improve myself for someone else. For example, I learned to speak Cantonese and Mandarin (although not 100% fluent still) not for my sake but for the sake of a girl I liked back in high school. Is this a bad reason? Maybe, but the end result was I didn't get the girl but I learned and improved on a few other languages for the sake of someone I liked.

Then it led me to think, why do I do things? Do I ever really do it for me or do I do it because of the person I like at the time, which seems like it differs from season to season in my life. Although recently however I've noticed that I've liked this one girl for a while now, on and off in the past but it seems like the on and off business of the past has left and now it's more certain.. at least certain until she says I have no chance with her. Luckily that hasn't happened yet, therefore I will continue to have hope. In any event, my life choices and my successes do seem to be based on the relationships in my life. When things are going good in my relationship life, I seem to be more successful in life. When I've had tough times in life it's also because I've had failed relationships or none at all. Right now I'm not sure why my mind is so focused on finding that person for me. I think it's because the plans from my youth have pretty much gone down the crapper and I'm just afraid of what will happen now. Now one might wonder do I still do things for other people? Of course I do, but is it bad? I'm not too sure it is. If it improves the quality of your life and the life of those around you then it doesn't really matter for what reason you do things, does it?

I guess whatever your spin on this all reasons at heart are selfish. Aren't they?
