One can't be a good marketer if his/her efforts are in product/client area only. The main product for a marketer is himself/herself. Self-branding is extremely important to a marketer.

I've heard from a collegue of mine that one of marketing gure started his seminar with a statement that he doesn't care about self advertising - his clients are the world-of-mouth channel. But to me this was a bit arrogant to say - very self-important and nothing about the audience.

The good example for me is Igor Mann with is slightly out of reality "I love all" image - he provides with a serious content without this burde of self-importance.

It is very important to show self-importance without showing it heavily.
