The regular study doesn't give practical knowledge to students. So Govt. of India has started Skill Development Program to train the students. Skilling is very necessary for students. Skilling makes them smart enough to do other jobs with their regular jobs. Trade education is necessary. In Basic, Education Bapu provoked to give handicraft education. Basic Education is the need of time. It makes students practical enough.
Service to mankind is service to God.
As expressed by Mr. Mohan the specialization what we are doing can earn a job in that field and we can survive. But if we have an additional skill in our hand if will come in handy to manage the family in case of any problem to our regular employment. Even during regular employment period also, if we have a skill in our hand that can be utilized by us in our spare time to make some extra money.
One of my friends was working as a general manager in a private company and earning a good salary. He practiced astrology during his spare time and earned a very good name. Now he has resigned from the job and became a full-time astrologer.
I feel everyone should have a second source of genuine income. For that these trades and specialties will come in handy. Ladies while managing their house are trying to earn some money by doing tailoring and other similar jobs without moving out of their house.
It is always good to have an additional skill in our hand for a better life.
