The next time you're tempted to go out because you're bored or stressed, go for a walk, lift weights, or work on yourself. Use that pent-up energy to build the life you want instead of wasting it on a habit that weakens you. Your future depends on your self-control.
It's not about seeing it as a sin; it's about protecting your energy. A man who wastes his vitality locked in his room staring at a screen is weakening himself by choice. Regaining control is the first step to regaining physical and mental strength.
