How do you know if you are being persistent or tenacious? They are both good traits to have but which one is better? Which on is a characteristic that you would like to add to your portfolio of traits? If it were me it would be tenacity. Being persistent is like having business cards with you in case you run into someone and want to give them your card where being tenacious is when you go out searching for people to give your card to and to pitch new prospects. Simply put, you don't just promote your brand, you become your brand.
