The Pyramid of Success #7 Self-Control 

Quote: ''Practice and self - discipline and keep your emotions under control''

Self-control is an important block in this pyramid. The reason why this is a very important is because self-control is needed when you are doing any work or goal. For example, if you are doing an assignment for school and you are frustrated you will automatically give up. If that same student had self-control then they wouldn't be mad or upset. The reason being is because self-control will help you  get over frustration. There is honestly yo need for frustration in ones life. Frustration brings anger and stress. These are the principle negative thoughts or feelings you should get rid of because they will have a negative impact in your life. Since life is limited self-control is something you should definable have. Without self-control you wont be able to control your feelings or actions. At times you might need someone to help you with your self-control, but that's fine because at least you want to fix the problem you have. Seek out for help when in need for self-control or even self-confidence.
