This is the most important thing to remember of all! Why, oh why is it so hard for me to have patience! so that's something I really need to work on in my personal life. Having patience and keeping on going even when I mess up a little bit.
It will hurt. It will take time. It will require willpower. You will need to make healthy decisions. It requires sacrifice. You will need to push your body to its max. There will be temptation. But, I promise you, when you reach your goal, it's worth it.
