There is a difference between conceit and confidence. Conceit is bragging about yourself. Confidence means you believe you can get the job done. — Johnny Unitas

If you want to get the business, you must instill this kind of confidence in your potential clients. In order to instill it in others, it must first be inside you.

If you sincerely believe your service will solve their problems, don’t worry about coming off as egotistical. If you can back up your claims, you’re no longer a braggart, you’re a solution provider.
