There is no force more potent than love. If you have it, you don't need to have anything else, and if you don't have it, it doesn't much matter what else you have. As you look back upon the events in your life you will find that the moments that stand out, the moments when you have really lived, are the moments when you have done things in a spirit of love. Therefore, search for love. Once you have learned to love, you will have learned to live.
Love is the most important ingredient.
By When the world gets you down, put things in perspective. See things for what they really are. Don't let the little things get in the way. Do what you can, however you can, with the resources you have available to you. And they will.
