I’m gonna concentrate on health and fitness but this is true of nearly everything in life.  If you actually follow through with the workout plan or the diet they all work.  If you go to the gym and lift weights you’re gonna get stronger.  If you run everyday you’re gonna gain endurance.  If you stick to the diet you’re gonna lose weight.  Most people talk about the “diet” or the “workout” but never actually do it, or give up too quickly.  P90x, Crossfit, Running, Veganism, Paleo, Atkins…they all work, you just have to do them.  Just do it for fucks sake.
