you cannot let anyone around you take you off your game. You cannot let their words, their peer pressure, their attitude, affect your discipline and your drive. Stay away from such people, and make your discipline a bigger priority.always do what you say you will do, and never leave a task unfinished. Not only will this show that you are dependable and a person of your word, but it is a very good way to boost your self discipline.
One of the most important aspects of self discipline, is having goals, and doing all within your power to accomplish them. Goals can provide you with the needed drive and motivation to follow through and overcome any obstacle in front of you, thus creating powerful self discipline.Whatever they might be, try to rid your life of habits that can either hinder your discipline, or put a negative spin on your situation. Remember that anything negative is not helpful to your discipline, whether it's attitude or behavior. Self discipline is literally something that you can teach yourself with practice. It's only by getting up and getting your hands dirty that you can start to incorporate discipline within your existence. Only then can you truly experience the ups and downs that it takes to become truly self disciplined. Regardless of what you do, you need to be aware of the rules, so that you can make better decisions on what you will and will not do. Educate yourself so you do not make ignorant mistakes.
