Displine Notes

According to Merriam-Webster, discipline is defined as "control gained by enforcing obedience or order.  Behavior in accordance with rules: orderly conduct."  It can also be defined as a "an activity that one engages in regularly to train or improve oneself."

 

The etymology of the word discipline originates from the Latin disciplina (instruction, teaching, knowledge) and discipulus (learner, student, follower).  It is rooted in the verb discere which means "to learn."  ​

​

Originally it implied training and instruction and later evolved to include punishment in the 13th century.  

​

What is the significance of discipline at The Cultivated Self?  It is the start of any change.  When we recognize a change that we want to make, we are filled with ambition and hope.  However, as we all find out, change is hard.  It is easy to show up to the gym the first week.  But the second week?  How about the 26th week?  How about after you have done it for 20 weeks and you just want to sleep in that one day?  That is exactly where discipline comes into play.  

​

Discipline is doing the tasks, the promises we made to ourselves, even when we don't want to.  It's performing the action on the schedule even though is going to be hard.  It's doing it, even though it sucks.  With enough discipline, we start to form habits.  As we form habits we start to really change who we are.  But if we don't have the discipline to stick to it, to push our way through the crappy moments, then we just revert back to our old habits and stay the exact same version of ourselves that we wanted to change in the first place.

    selflessness. We are by nature flawed and inconstant creatures. We can't even keep

    and excitement, not for careful attention to detail. Discipline is something we have to
    work at.
