And neither are you. Nor should you want to be.
The term ‘guru’ has become so over-used and redundant that it’s essentially an insult. It’s up there with ‘social media maven’ and ‘internet marketing expert’ as labels that nobody should want or encourage. Putting aside that no one person can possibly ever know enough about these vast subjects to actually consider themselves worth of such a title, the terminology is so trite, and so cliched, that just hearing it being used in any kind of proactive manner physically makes you cringe.
So if you’re actually describing yourself in this way it tells us two important things: one, that you almost certainly know very little, and two, that anyone who wants to know should avoid you like the plague.
