David Ogilvy is known as "The Father of Advertising" and was called "the most sought-after wizard in today's advertising industry" by TIME in 1962. All in all, he was the man, one hell of a creative, and dropped wisdom regularly. Here's some sharp life and creative advice he gave over the years.

1.) “The best ideas come as jokes. Make your thinking as funny as possible.” 

2.) “I don't know the rules of grammar. If you're trying to persuade people to do something, or buy something, it seems to me you should use their language.” 

3.) “Hard work never killed a man. Men die of boredom, psychological conflict, and disease. They do not die of hard work.” 

4.) “Where people aren’t having any fun, they seldom produce good work.” 

5.) “Develop your eccentricities while you are young. That way, when you get old, people won’t think you’re going gaga.” 

6.) “If each of us hires people who are smaller than we are, we shall become a company of dwarfs. But if each of us hires people who are bigger than we are, we shall become a company of giants.” 

7.) “Don't bunt. Aim out of the ballpark. Aim for the company of immortals.” 

8.) “Never allow two people to do a job which one could do."

9.) “In the modern world of business, it is useless to be a creative, original thinker unless you can also sell what you create.” 

10.) “It isn’t the whiskey they choose, it’s the image.” 

11.) “Advertising is only evil when it advertises evil things.”

12.) “Concentrate your time, your brains, and your advertising money on your successes. Back your winners, and abandon your losers.” 

13.) “The more informative your advertising, the more persuasive it will be.”

14.) “Hire people who are better than you are, then leave them to get on with it. Look for people who will aim for the remarkable, who will not settle for the routine.”

15.) “The pursuit of excellence is less profitable than the pursuit of bigness, but it can be more satisfying.”
