Self Discipline - What is it?

"Self-discipline is the ability to get yourself to take action regardless of your emotional state."

"Self-discipline is perseverance, restraint, endurance, thinking before acting, finishing what you start doing, and as the ability to carry out one’s decisions and plans, in spite of inconvenience, hardships or obstacles."


"Self-discipline is self-control, the ability to avoid unhealthy excess of anything that could lead to negative consequences."

"Self-discipline is the ability to forgo instant and immediate gratification and pleasure, in favor of some greater gain or more satisfying results, even if this requires effort and time."

I find myself wondering what is self discipline and why is it such a difficult thing for so many people to have. What about having the ability to say no is so difficult? What about thinking further than 'now' is something people have to learn to do?

My biggest question is why is it so hard for me?
