At the very beginning of my career, when my employer had asked me to do my first ever sales call, I presented myself (in German) by adding the definite article “the” to my name – In German, we can do that. However, this shows that you are diminishing yourself. This also reflects a lack of confidence. My mentor pointed it out to me immediately, and I changed it on the spot. It is crazy how this seemingly minor change helps growing into your professional role.
