Self-discipline is one of those overused words that people have a hard time explaining. It’s filed under the category “easy to recognize but hard to do”.
I’m not going to waste time telling you about the benefits of self-discipline because if you’re reading this, you already have enough reasons of your own. To make sure we’re on the same page, here is my definition of self-disciplineWhat you are “supposed to” do should only be determined by you and no one else. If you let others decide what you are supposed to do, you’re no longer building self-discipline, you’re building obedience.
Most people don’t have problems doing things they feel like doing. The real issue is doing the things they’re supposed to do when they don’t feel like doing it. Examples that come to mind: going to the gym after a long day of work, not eating your favorite dessert because you’re trying to lose weight or waking up early to always be on time.
