The book was published in 1936 and sold over 30 million copies, making it one of the best selling books of all time. Carnegie has been conducting business education courses in New-York since 1912. The truths on which this book lays down are too meaningful to be known.

However, the book mainly discusses on how to be friendly and spend a smiling life. This tells us to smile and be friendly, not to argue or find fault to get the other persons’ point of views rather encourage and praise them, let them talk all the times they want to and persuade he has very good ideas of talking.

Further the author advises to never tell another person that he is wrong, but add that if we are wrong ourselves, we can turn an ability into an asset by admitting it quickly and emphatically.

“If we do all that, we are pretty sure to win friends.” Nicely elaborated in the book. And if, in addition, we have to win our own ideas, salesmanship will profit the more.

Mr. Carnegie’s book offers very good advice on bad assumptions. The good is in the simple, sound, practical advice of Mr. Carnegie’s counsel and the lively and well – illustrated directness with which it gives. But there is a bad suggestion too within it that the superficial cultivation of ” Personality” may take the place of a sound foundation of knowledge, intelligence and ability.

By all means let us follow the sensible advice so cheerfully offered in Mr. Carnegie’s pages. And at the same time let us try to keep our balance and clarity of thoughts. You cannot gather grapes from thorns figs, from thistles and there is no royal road to any kind of success or happiness. But improvement is in fact and imagination may indeed make us more effective and more agreeable. A genius and understanding of our follow is a thing worth working for its own sake.
