I think I'm not alone in that every time I tell someone that I'm a UX Engineer, I'm usually met with a blank stare followed up by the question, "okay, what does that mean?"
I usually tell people that UX professionals seek to define and solve problems. For me, that means that I work to make my company's stock trading and client management website as simple and user-friendly as possible.
I'm a big believer that the best UX professionals can come from any walk of life, so long as they are passionate about problem solving and have an unquenchable thirst for knowledge of the profession. I'm sure y'all are bored of hearing me beat that drum time and again, but it's so true.
In the end, we are all apprentices in a craft where no one has ever become a master. No one knows everything about UX-- even some of the best minds in our industry often disagree over some of the fundamental building blocks of our practice.
The more we study, the more we learn-- and the less, it seems, that we actually know. I've often thought that the Dunning-Kruger Effect (the notion that those with low ability often see themselves as experts on a topic) needed a corollary that those with high metacognition of their own weaknesses often underestimate their own ability. Knowledge is a gift, but it comes with a price. It's only in glimpsing the depth of Fountain of Knowledge that we can truly appreciate the shallowness of our own cup.
Keep working hard, stay passionate, and learn something new every day. You are more knowledgeable thank you give yourself credit for being, and you will become more than you think you can.
