I always thought that being disciplined meant knowing where you had to be, when you had to be there, and what you had to do on getting there. I thought it meant getting up every morning and having a day full of things lined up for you to do. It meant having lists and timetables and plans that won't fail you if they/you tried.
Discipline meant being able to do something, and see it to the finish. It meant trying and not giving up. Even when you're tired and uninspired and sad and just plain lazy.
Disciplined meant doing just what you set out to, accomplishing it, and sitting down at the end of the day, with a tall, cool glass of diet coke, and feeling like you mattered.
Discipline still means all of that, and some.
It may not always need a plan or a schedule. It needn't mean i give something hours of time and energy.
It means i do it. One day at a time. One hour, if i need to.
It means i listen to kabir (the doha person familiar to those who took second language hindi in cbse schools), and do what i have to. Now.
