I am not sure how discipline is different from consistency or similar to it? But I believe discipline is everything!
I have experienced a range of people with tremendous potential who just fell apart at the moment of truth only because they were distracted. The first time when a friend did not get admitted to his choicest schools because he did not make the qualifying threshold, the second time when an acquaintance failed to deliver because he failed to prioritize consistently. It is the discipline of to stick to the task, the disciple to bring it elevate the issues, and so on.
Be it putting away your toys as a kid, completing and submitting your homework, studying the coursework, doing laundry, exercising or simply developing skills to upgrade and keep pace with the evolving talent market and aspirational goals.
Franz Kafka (1883 - 1924) - "There art two cardinal sins from which all others spring: Impatience and Laziness."
Life is all about hedging, we place bets on outcomes in the future based on an unsaid, unwritten commitment to put in the best effort... isn't that really a commitment to be disciplined and consistent in the effort until completion of the task.
For some reason our performance measurement systems do not track discipline explicitly instead they seem to measure quality and quantity relative to the peers?
That’s rather strange.
