Veronica Campbell-Brown has been involved in athletics for a very long time, and has a reputation for always giving her best and creating history in almost every race she has participated in. We can look at her consistent performance as a result of much discipline and training.

Discipline
This means developing and sticking with habits that help you to achieve your goal, even when you don't feel like it and even when it gets hard. For Veronica, this means regular training and practice. She has to practice her race start, turning corners for the 200m, do various exercises, and eat healthy. I'm sure she doesn't always feel like eating vegetables instead of fast food, but discipline is about making the decisions that will benefit you in the long run, and sometimes that means refusing to do what will gratify you now.

Confidence
If there's one thing you can say about VCB, she always looks calm before and after her races. In fact, you hardly see her getting agitated or displaying nervousness and fear. This is the result of confidence, which is that quality in winners that makes them sure that they have what it takes to win.

Usain is another example of confidence. He's so calm, he can even play around with the cameras before races. Confidence is the result of hard work and training. If you've practiced and properly prepared, you  can feel confident that you will give nothing less than your best on your big day.
