When you are content, you can live with less eating, less drinking, less drugs, less (or no) cigarettes. There is power in happiness and contentment.
So much of our thinking has been shaped by the movies, and the movies teach us to go fight the enemies out there; have some car chases, some gun fights, a setback, another car chase, another gun fight, then a final battle with the villain.
In reality, the big war is with ourselves first and foremost. Conflicts with others usually originate with ourselves. Being chronically happy is strength; it’s like being physically fit, or smart.
Let yourself be happy. Don’t think it’s a weakness, and that you have some obligation to be miserable because of the bad things we are facing in the world.
