Selfless Deed

I was watching Friends the other day, and for once in the history of the show, Joey had actually said something that in a way makes perfect sense. A brilliant theory might I add. 

"There's no such thing as a selfless deed..."

It's true. I always thought that whilst performing a good deed, you might dub yourself as a selfless person for taking up the time, resources, and energy in helping others when in reality it doesn't hold any benefit to you whatsoever. That your acts come from the kindness of your heart. However, I would like to add that I agree with Joey when he says that there's no such thing as a selfless deed. Think about it, whatever you do, you'll always get something in return. Be it material incentives or non-material incentives. For example, my sister might ask me to help her with her report, I'd do it in a heartbeat but in return, she'll help me with my report. The same thing goes to non-material incentives which are mostly psychological incentives in which for example, I might help a complete stranger in something and yes I won't get anything in return, but I will have a sense of satisfaction and I would feel good on the inside because my supposedly "selfless" deeds, so in the end I got something. I felt good about it in the end so I gained something from my deed. 

I know it might be confusing and the way I'm explaining might not be so clear, but do you get where I'm going with this? I never thought about it this way, and when I first heard it I thought it would be interesting to share.
