Once upon a time in Japan, when I was an exchange student, I read an old, almost ancient philosopher who said that a person who has less time would be more successful in study.
In contrary to the common belief, people with limited time will work harder,optimising their opportunity to study. And then, miraculously, they will succeed.
Well, not miraculously. It's a purely simple logic.
As agreed by more recent wisdom: "if you want the job done, ask the busy people to do it."
Now it's up to me to prove what the Japanese philosopher advised centuries ago!
