What I mean by getting the right knowledge

In every man's life there is a stage when he is supposed to go to school and earn knowledge. According to the Vedas also, in a man's life first 25 years of life is only for studing. Parents also says that to earn knowledge and to got success in life everyone has to go to school. I also have done that for the last 23 years, but if I go through my life and the phase after my school (Specially the last 4 years), I feel that the knowledge which I gained from the outside world is much more than those I got in the school or college. I also feel that the book knowledge is necessary but it is not at all efficient for anyone. The main knowledge one can get is by experiencing and facing the world by its own and taking his dissicions by its own in the time of any problem. Because I think practical knowledge in life is always important than any other knowledge, and the practical knowledge in life is the most important of all. It is also important for get into any debate which we face everyday in some or the other matter (sometimes correct and sometimes unnecessary). We should give any advice to others if we have the experience of our own. We should also have some main key knowledge in all the fields which is concerned with us or not, as it not have to seem to concern with us today but if we have some key knowledge of the subject it would help us later in the life if we face it. Not only having the knowledge in every matter will help but also we have to update ourself with the surroundings and the matter, otherwise inspite of having the knowledge, we will not be updated with the latest facts with the subject ( As today in every field there is a very fast change everywhere)
Today, I thank God and Ebiz for this practical knowledge which had made me a complete man to face the world, and also helped me in succeed in life and to take the right discisions not only for me but for many others too...... Sometimes, when I sit alone I think that what would be my life be if I had not got the opportunity(via EBIZ) to interact with the 1000's of type of people and their mindset over any issue and life.
I have tried a little to give my feelings on having the practical knowledge in life..........which I think will help everybody if they understand it clearly and correctly.
