[header] How to discipline yourself efficiently [title] Eat healthy : [step] This is a golden rule. Eat at least 5 fruits or vegetables a day and avoid fast food at all costs. Gather up all the food in your house that you like yet that you know is bad and burn it/throw it away. <sep> (A) Find something healthy which will help you to behave more correctly, no matter what. Whatever you eat should be fresh and healthy (but you can stuff it in a long plastic bag), like whole wheat pasta with fresh vegetables and/or lean meats. (B) Even foods such as coffee and energy drinks which claim to help you will only worsen your mood and overall health. Avoid alcohol and cigarettes/illegal drugs are a no-go. (C) The more fruits and vegetables and more processed food, the more calories your body sends out and the more calories your body searches for the good stuff in your body. Choose all foods that are low in calories, lower in cholesterol, water, vitamins, and fiber. (D) Don't procrastinate, as this makes it harder for you to concentrate and think more clearly at the end of the day.
