The Science of Self-discipline is a new book that I have been reading for a couple weeks now. It is written by Peter Hollins a human psychology researcher who is best known for his work on practical strategies on self-improvement, psychology, and personal development. He works with and teaches people how to unlock their potential and how to achieve success in life and he has put all of his teachings and research into this book. In this part of the book he is explaining Aristotle’s Theory of Motivation. Aristotle is a famous philosopher who created the original guides to human motivation. In this part he says how you should know what are the better motivations and to chose them over the negative motivations.
It’s up to you to be disciplined enough to avoid and resist negative motivations and to have a clear understanding of the positive motivators that can help you maintain self-discipline.
This quote means that it is the persons choice to know and be Disciplined enough to resist any negative motivations or habits that could affect them in the future like eating unhealthy foods or not doing work that you have. They have to have a good and clear understanding of the other positive things that will help them later on and to help them maintain self discipline. That is what he means in this quote.
