Self-Discipline

[Sultan Mahmud Sujon]

Marietta wakes up before dawn each morning to exercise. She works very efficiently in the office, ignoring distractions, and devoting all of her attention to high-value projects. In the evening, she attends a class online; she'll be graduating in a few months with her MBA.

How can people like Marietta achieve so much, so consistently? And how can we accomplish as much in our personal lives and careers? Part of the answer lies in self-discipline. This is what pushes us to deliver on our best intentions and goals, even when we don't feel like doing so. If we have self-discipline, we are able to put off short-term pleasure (or endure short-term inconvenience or discomfort) in the pursuit of long-term gain.
