We live in an addictogenic culture. Bad habits are very often more immediately attractive, exciting, pleasurable and comforting. The good habits are a bit like a desert: dry, difficult and hard work.
Balance and inner harmony are about allowing the flow and respecting when it's time to sleep, when it's time to work, when it's time to eat, when it's time to run. When you start to get in tune with yourself and your body, the inner wisdom guides you.
