We have the choice of which pain of these two we will experience ...
The pain of regret OR the pain of discipline
Which one do you want to live?

The pain of regret is going to be much more difficult ... than the pain of discipline.
It is certain that discipline is not always easy, but will produce so much satisfaction, joy and encouragement as the pain of regret.

There is nothing more wonderful than to have done, to have tried, to have worked on our dreams than to have only hoped ... and finally to experience the regret of not having persevered in the discipline of our dreams and goals!
