As you go through life, you'll meet and intereact with a lot of people. Sometimes, you will disagree with what your partners, clients or friends have to say about a topic. These times, though they may be frustrating, will help you grow. The more you deal with people, the better you will become at dealing with people.

Specifically, in business, don't sell yourself short based on other people's opinions. Be confident in the work that you do. You know what you are worth, don't let other people decide that for you.
