Life is precious. Love yourself enough to take care of your health. Exercise. Eat well. Make time for self-care. Treat your body right because it is the only one you have. When you have no health, you have no life.
Why talk about what we want? That is childish. Absurd. Of course you are interested in what you want. You are eternally interested in it. But no one else is. The rest of us are just like you: we are interested in what we want.
