only so far as it enriches your life, that is literally the definition of selfishness
I'm sure we'd all be better people if instead of helping others, we spent time judging and bashing those who spend time helping others but don't have the proper frame of mind when doing so.
Then we could get into the whole philosophy 101 debate of "Does truly selfless behavior exist?"
My intention was not to criticize anyone for spending 100 hours helping others. I am saying that if you've already spent 100 hours helping others, and someone asks for your help, you should ask yourself "is helping this person the right thing to do according to my values", not "will this increase my happiness."
