A teacher doesn't brag about what he does, he simply teaches.
A guru doesn't tell the whole world that he's a guru...he simply gives advice to those who need it and people are left thinking, "that guy is a guru at this particular skill".
On the negative side..
A robber doesn't say, "Im going to rob you tonight".
A con artist won't say, "I'm conning you right now".
And this brings us to the ONE SILLY MISTAKE that I think majority of internet network marketers commit:Telling Instead Of Doing.
More Talk...Less Demonstration.
Let me give you a few examples:
"Hi I'm XXXX and I teach people how to open 1,984 Income Streams"
"I'm a network marketing mentor, opt-in below"
"I'm a professional coach and internet marketing expert......"
There are more better ways to brand yourself and your expertise without directly telling people about it. In fact, it is much more effective if you don't tell it upfront because people hate egotistical freaks. Just let the things you do, your free stuff, your products, your customer service, and everything about your business DO THE TALKING AND BRAGGING FOR YOU.
Do more, and promise less. It always works.
Hope you find this useful. Have a great day!
