"Service to others is the rent you pay for your room here on Earth."
You can pray and fast as much as you want, but helping others is also a form of worship. If you live your whole life in a selfish bubble, then there is barely a point to it at all. We all like to have fun, acquire money, enjoy material things, and participate in other human activities, but no one should occupy this earth without "paying rent" by helping their fellow human beings who may not be as fortunate.
How do we begin to create a life of service that will give our lives meaning and touch the lives of the ones in need? The first step is to turn our good thoughts and intentions into actions, and then the rest will follow.
