A poet who lived sometime in between 1398 – 1518 known as Kabir Das in India wrote a couplet in Hindi which is
Karat Karat Abhyas te Jarmati Hot Sujan
Rassi awat jat te sil par parat nishan
In English rough translation would be
Practice, hard practice makes a dumb knowledgeable
Just like the rope moving on the stone year after year lives its mark on the stone.
So true. Look at the great players and athletes who practice hard for years to win those treasured medals and cups in their arena of sports. There are more number of wasted genius in the world then there are those who are successful. Even above average people with just perseverance and hard work achieve which many talented youngsters miss out just because they did not practice hard enough.
It has happened to all of us who have contemplated about finishing our courses when we were in school well before exams but procrastinated. With us there always those who were little dumb on the day when the course was being taught. While they practiced in private we just knew we knew. Come exams they always got better of us or touched us just by their sheer hard work.
The truth about hard practice making one perfect does not limit itself to the human species, look at the animal kingdom and we see that Lion or Tiger cub practices hunting to become one of the fiercest hunter.
We by our greater intelligence can perhaps learn faster but to be perfect there is no other option but to practice and practice hard.
