I've always believed fitness is an entry point to help you build that happier healthier life. When your health is strong you're capable of taking risks. You'll feel more confident to ask for the promotion. You'll have more energy to be a better mom. You'll feel more deserving of love.
It is ironic that the one thing that all religions recognize as separating us from our creator our very self-consciousness is also the one thing that divides us from our fellow creatures. It was a bitter birthday present from evolution.
