The CEO of a large worldwide business networking and development organisation only has pink shirts. He confessed to me having over 20 pink ones, and they’re even the same shade! It’s part of his brand, it’s part of what makes him memorable.
A very high-profile speaker in the personal development arena has a haircut lost in the eighties. Why? Well, again, it’s part of his brand.
Some people have a particular style of writing, some have a certain kind of jokes and some rely on clothes. Others use effective anchors in their speech.
To increase your staying power make sure you are memorable, and make sure that you show up in front of your prospect often enough, one way or another. In these days of social media and high noise, you need to have on average nine interactions before your prospect will buy. Make sure each one is memorable.
