Every one of us must have a mountain to climb. It might not seem any bigger than a molehill. The size doesn't matter. All we need is a meaningful reason to be engaged in the pursuit. Try something you've never tried before. You'd be surprised at how many options there are out there, be it tennis or golf or soccer or karate. It might even be a literal mountain. A challenging goal like an alp changes my daily workout into something quite exciting.
