" In a situation such as today, by contrast, where people constantly have-or think they have-to decide what to do, they will almost invariably be governed by feelings. Often they cannot distinguish between their feelings and their will, and in their confusion they also quite commonly take feelings to be reasons. And they will in general lack any significant degree of self-control. This will turn their life into a mere drift through the days and years, which addictive behavior promises to allow them to endure.
Self-control is the steady capacity to direct yourself to accomplish what you have chosen or decided to do and be, even though you "don't feel like it." Self-control means that you, with steady hand, do what you don't want to do (or what you want not to) when that is needed and do not do what you want to do (what you "feel like" doing) when that is needed.
