I totally agree with you. Commitment, a word when pronounced sounds deep, filled with a lot of pressure and high results.
Just like the example you gave , using those excellent athletes. Hmm, i would say it also implies in life. Everyone has high expectations, same as everyone has high hopes on me and you. For what reasons? I don't know. And that's why we have to try to do our best to succeed.
We are driven by the want to achieve something, to leave a mark on the world in some way. If we can't feel it by doing something ourselves, we do it vicariously.
Very true Sir, sometimes this wants or desire to be great, make us go extra miles to get them. Some are in a positive way. Just like how those athletes worked day and night to achieve those gold medals.
