Isn't it always for your own?

You give something to some else who needs to more then you. You get a good feeling, if you didn't you felt like shit.

You catch a bullet for someone you care about because otherwise you couldn't live with youself anymore.


You get asked a favor. You do it, expecting them to do the same for you.

Etc etc


So at it's core, isn't it all just selfishness really?
