To help others

A guy told me that 'the best way to solve our problem is by helping others to solve their'
I used to be didn't understand with the message of that quote. But he told me, that there is one of benefit by helping other:

we will forget a while to our own problem. it's like a relaxing way from and 'little escape' from our problem. we will be less stressed, you have another thing better than being 'Mr. ME&ME' who is just focused to our own problem.
