It would depend on what one considers "better." Some people think improving their physical fitness makes them better while others instead focus on improving their mind. Being better could mean becoming more nurturing or it could mean taking a stand against injustice. Too many people think being better relates directly to the amount of their disposable income.
The people I most admire are those that risk their lives to expose government corruption despite all the wolves and sheeple standing in their way. I know this makes me "better" because people who blindly trust their leaders often fly into a rage complete with utter denial when I point out their leaders' dark side. People will even go to extremes trying to prevent the message from spreading. Making enemies is an unfortunate side effect of social responsibility.
