Just Do It.
Such a strong statement, and something to live by. I'm tired, Im not sure if I'm gonna work right- just do it. Get off your lazy ass and move. Run around for an hour, walk to the park, or if you want go to the gym. Just get your fucking body moving. Its good for you, and hell if you are in a shitty mood- it gives you endorphin's- they make you happy. Try it.
Had a bad day at work and wanna nom? Don't grab that pizza. Eat something healthy. Yeah, its not gonna be the same as 3 scoops of custard but in the morning you will feel better and not be self-loathing. while in the shower. Just eat right. Just do it.
