“Discipline is superior to motivation.”
I took this line as my favorite item from a life improvement blog post 100 Tips for A Better Life. Discipline is a choice, whereas motivation is a feeling. If we choose to be disciplined in the small things, we will become disciplined in the large things.
I have had to pour massive amounts of energy into unmotivated people, mostly because I see what they can be where they cannot or will not see it. This is energy that could be directed elsewhere in a more productive manor. Whether you are motivated to do what you do or if you are having a particular unmotivated day, your habits and your discipline will keep you making progress towards success. It is the only way. It is how you become successful over the long term. To borrow from Navy SEAL Jocko Willink, “Discipline equals freedom.”
