This is a great sentiment. Sometimes you merely need to look closest to you to make a difference and ‘be of service’. When you are of service in the world, you create a better existence for yourself and all of humanity.
Who is next to you right now? A spouse, co-worker, customer, friend? A random person? How can you be of service to them? Perhaps you can simply be kind and compassionate in this moment? What can you do to reach outside of yourself and touch another soul?
When you think this way your life takes on meaning, and this meaning can make the difference between a life filled with fear and one filled with joy.
