I guess I am sort of hyper sensitive with this because I would be no means ever call myself a wordpress expert. I tinker with wordpress a lot with it being my preferred CMS. At my agency they try to sell me as a "wordpress expert" which puts a lot of expectations on my performance when I never declared or claimed I was an expert.

This comes with the price of me being seriously stressed out/working overtime without pay (because I am salary) to find a solution to every problem to make sure our clients are happy. I generally do find a solution because I tinker enough but it takes me much longer than an expert.

My job title changes daily too. Sometimes I am a Wordpress Expert, Creative Direction, Production Artist ... Digital Designer.... whatever sells a pitch to a client I guess.
