"He must be independent and brave, and sure of himself and of the importance of his work, because if he isn't he will never survive the scorching blasts of derision that will probably greet his first efforts"

This quote by Robert E. Sherwood is highlighting the importance of having a strong sense of self and purpose in order to be successful. He is recommending that anyone who is attempting to do something new and innovative will likely face criticism and ridicule from others. In order to overcome this, one must be independent and brave, and have a strong belief in themselves and the significance of their work. This will give them the strength and strength to persevere despite the unfavorable feedback they might get. It is important to keep in mind that success frequently comes from taking dangers and having the nerve to defend what you believe in.
