Discipline is not running a marathon. It is not losing 50 pounds. It is not walking across Turkey.
Discipline is running one mile, and then waking up the next day and running two miles, and then waking up the next day and running three miles.
Discipline is losing one pound, and then waking up the next day and losing the second pound, and then waking up the next day and losing the third pound.
Discipline is waking up knowing the entire day’s work could easily be covered by a car in 10 minutes, and then doing the work anyway. Discipline is being on the verge of tears because you’ve said goodbye to someone very important to you, and then doing the work anyway. Discipline is every day having a reason to not do the work, and then doing the work anyway.
Discipline is not the end result. It is how we get to the end result. Discipline, and its close relatives patience and faith.
