As there is a famous saying that "Learning is never ending Process."
As per my Experience while learning we should always at our toe or enthusiastic enough to welcome the new things even from Younger one's.
A person when thinks he has very minimum knowledge of particular field can only learn more fastly & perfectly. While learnig Keep asking questions when ever you have doubt otherwise one who hesitate to ask doubts also hesitate to open up himself & cannot become a Good communicator.
Now a days in this Globalised era people survive only if they can communicate well.
These things are known to many but they commit same mistake of not communicating properly. A good coomunication directly helps a sound learning.
Learning new things is also a Good Habit to stay away from wrong paths.
Therefore learners should have a enough enthu & zeal to grasp more things to become a respectful Human being. After all we are here to spread Love & not hate. God Bless all.
