"Life is easier when you enjoy what you do"
This learning process is not applicable to the doctors alone, it holds good for the scholars, professors and all who are in quest of knowledge.
Thoughts exchanged is knowledge gained.
A teacher who teaches a subject will go deep into the subject and improve his/her knowledge further and learns new ways of teaching. My teacher at University used to give very good examples during teaching and those examples were so good that we will never forget. This will come by practice and reading and rereading the subject again and again. A teacher will be getting updated the new developments of the subject he is teaching so that he can teach the students also about the developments.
Believe in the existence of God the super power.
