The only thing that's keeping me going is the thought of making other people happy.
Is that really the only thing that makes you happy?
Yeah, the only thing that brings me happiness is the thought of being able to help others improve their lives.
Everyone has their own reasons to keep living. If yours is to take care of other people that's an honorable thing.
I agree and it feels good.
I'm sure as you continue to do good things for others and make them happy, you'll become more happy yourself.
