1. You have enough. You have everything you need in order to live, you are living in excess, among clutter, yearning for more. Take a breath and tell yourself, "I have enough." Remind yourself that the important things in life are not things at all.
2. Focus on the things you need to do instead of the things that you "need" (i.e. want). Focus on being present, on being kinder & building your knowledge, in being more charitable & strive to build a stronger connection with your Lord.
