Discipline

Staying true to your excercise routine and your health requires discipline. Do not look at it as a punishment or a burden. You have to earn your body if you want to get healthy, look good and feel good. There is no magic pill. There is discipline. Being prepared is the key. Cook your meals ahead of time. Pack your clean meals/snacks and take them to work with you in a ice chest.
Keep healthy snacks in your car so you are not caught starving and end up eating fast foods or processed foods. Don't give up. Your health is worth it. Respect your body. Earn your body. This is not easy, it won't come easy. This is discipline.
