" Appoint an accountability partner—someone whom you report to regarding your chosen goals and keep updated with your progress in achieving them. An accountability partner sees to it that you are on track to fulfill your commitments. This offers you the hugely effective combo of positive support and praise when you retain self-discipline, along with social pressure and the risk of disappointing someone important to you when you don’t keep your commitments. The Hawthorne effect is a phenomenon in which people change their behavior to be more pleasing and positive when they know they are being observed. You can take advantage of this tendency to improve your own self-discipline by making your behavior more observable to others, thus giving you that extra push to do what you promised you would so that you impress others or at least don’t let them down. Seek out a role model or mentor whose qualities and behaviors you can emulate. As you get to know your role model better and observe their methods more closely, you become more inspired and informed as to how you can apply their strategies in building your own habits of self-discipline.
