MIND OVER MATTER
I love the saying MIND OVER MATTER and I believe and stand by it cold-heartedly. That's how I get through the times when I feel like I can't or I don't want to any more... Physically, your body can and will give up on you - but your mind is so much more powerful and stronger than anything thing you can possibly think of. You can change how you feel and how much farther you go with just a mental push to yourself.
It's the conversation that you have with yourself that pushes, threatens, and screams at you. The voice that tells you that you can and you will do whatever you set your mind to do. Even though it's harder than you thought, you are going to get to the goal ahead of you.
So just remember - MIND OVER MATTER. If you mentally push yourself everything else falls into place.
