Friendship exists outside our modern economy of scarcity... It's not about apportioning vanishing resources of time and energy. Friendship is a blessed relic of the ancient economy of the gift, and the time freely given to people dear to you actually creates magical abundance.
We need to strengthen such inner values as contentment, patience and tolerance, as well as compassion for others. Keeping in mind that it is expressions of affection rather than money and power that attract real friends, compassion is the key to ensuring our own well-being.
