1. Keep running. Commit to it. 3x a week. Make it as important as work and almost as important as loved ones. Definitely more important than tv.
2. Meditate, though feels impossible. Start with 3 minutes, work your way up.
4. Convince yourself that your whole entire life is how you make it, how you react to it, how you respond. Happiness or unhappiness is less about what happens and more about what you do in those situations. This one is going to be hard. Keep trying.
