Power

To conquer anything or anyone, to be able to achieve something great, to do anything worth doing at all, you've got to first believe that you can.

Many of us seek self control in various areas of life; in abstaining from food as part of your diet plans or during a fasting period, or in taking time off social media for personal reasons, or taming your tongue to speak only kind words, or to stay dedicated to your workout routine, anything. To be able to control yourself and stay true to your plan, you have to train your mind to believe that you'll survive without that thing. Train your mind to believe you can do what you want to do and achieve your desired results regardless of the painful discipline you may need to endure.

It all starts in the mind.

To tame your flesh, you'll have to first train your mind. The flesh usually carries out actions the mind has thought to be desirable. 

Start the real battle, control your mind, watch what you let in for it slowly becomes a part of you.
