This isn't being greedy. It just helps you feel your power. Later on you can give it away, burn it, keep it, whatever, it doesn't really matter. As long as the decision is yours, you'll feel good. Do one small thing to improve your health.
Good health is some of the best pampering.
Whatever it is, start planning on having it and take one small baby-step towards getting it. No matter how big or small that outrageous luxury is, the process of planning is half the fun. Whatever looking good means to you. Stop doing something you've always done, start doing something you'd thought you would never try. There's not much in our environment we can totally control.
