to help is different than to actually help
I occasionally think 'bout this and recently found a very interesting article.
Basically, to help people make you feel happy, but it doesn't always mean that what you did made them happy.
Currently I'm not into community services so occasionally doing the 1st part (to help) is enough for me. However, if you really like to help people, you might need to think 'bout the 2nd part (to actually help) : )
