Look at a person with discipline. Observe them closely. You’re most likely to see someone secure and successful. Discipline is a steadying force. In good times and in bad. When you have the advantage and especially when you don’t.
The same can’t be said for talent. A person with lots of talent is no more likely to be secure and successful than a person with average talent. Because talent isn’t a choice. It’s potential. It’s what can be capitalized on with enough of the right discipline.
