Either you or yr work has to speak up. Yes either MUST speak.
There are two kinds of brand building for all : self and product / services.
One is self promoter by its sheer nature or strategy. Aggressive advertising , marketing , self promotion , self talk etc. Making all out effort to be known among the target audience.
Second way is to do a kind work that speak for it self. It also requires speaking but here work speaks. Users of the work will speak and spread the word. When a company creates scintillating customer experience, its customers speaks. There was a saying that it is the best selling author and not necessarily best writing author who sells. However in times of powerful social media its the best writing authors will become best selling. Only sellers without the best content will be difficult now.
It is not always necessary that best sellers are not best content wise, however when users speaks rather than self /company , people believes most. Self sellers can be successful but when work sells - person and product not only reach up to the top but command respect also.
We have two shining examples of person whose work always spoke more than the self and they are on the top of their class : Guess?
Mr. Amitabh Bachchan and Dr Manmohan SIngh. Both r introverts , speaks less but cud reach to the top , sheer for the kind of work they did. You may add examples on both side.
Are you or your work speaks more than you?
