Be self motivated.
All your motivation comes from within yourself.
If you do not have the motivation to do something then you will not do what it takes. You will not push yourself when it gets hard. You will quit at the first sign of adversity.
Motivation can be created and generated by you. There must be a reward for your hard work. There must be something good to focus on when its hard and difficult. When you’re depressed and in pain you must go through adversity to reach the heavens.
