We are all advertising, all of the time. If you want to sell your car, what do you do? You clean and polish it and make it the best you can. Some people bake bread when they are trying to sell their house because the smell adds a friendly feeling. Even the priest, with all his or her fervour, is advertising God. Everybody is selling.
Risks are a measure of people. People who don't take them are trying to preserve what they have. Some risks have a future, and some people call them wrong. But being right may be like walking backwards, proving where you've been.
You need to aim beyond what you are capable of. You must develop a complete disregard for where your abilities end. Try to do things that you're incapable of... If you think you're incapable of running a company, make that your aim... Make your vision of where you want to be a reality. Nothing is impossible.
There are rules in advertising, and those rules are self-imposed by the client companies because they don't want their products to be seen as dishonest.
Everybody wants to be good, but not many are prepared to make the sacrifices it takes to be great. To many people, being nice in order to be liked is more important. There's equal merit in that, but you must not confuse being good with being liked.
