To love others you must love yourself. You can only give to others what you have yourself. This is especially true of love. You cannot give what you have not learned and experienced. Since love is not a thing, it is not lost when given. You can offer your love completely to hundreds of people and still retain the same love you had originally. It is like knowledge. Wise people can teach all they know and when they’re through they’ll still know all that they have taught.
