Studying, studying and only studying can create the person! The best teachers are eternal students, don’t you ever forget this rule!
You couldn't be more right about this, i got a teacher with 60 years and the first thing he told us is that even though he had been doing the same thing for 40 years he is still learning new thing everyday.
With every experience, good or bad, you learn something new, and what is life if not a big experience.
