You are wrong if you think that the joy of life comes principally from human relationships. God’s placed it all around us, it’s in everything, in anything we can experience. People just need to change the way they look at those things.
“I think you really should make a radical change in your lifestyle and begin to boldly do things which you may previously never have thought of doing, or been too hesitant to attempt. So many people live within unhappy circumstances and yet will not take the initiative to change their situation because they are conditioned to a life of security, conformity, and conservatism, all of which may appear to give one peace of mind, but in reality nothing is more damaging to the adventurous spirit within a man than a secure future.”
