Looking back at our careers, most of us have had to make a decision to either focus on a specific skill-set or become part of a management role where there is a real threat that one becomes a “paper pusher”. I remember vividly when I had discussions with my bosses in the past when I was asked whether I want to focus (vertical) or become a generalist (horizontal) in my career. We make these choices and sometimes we are being hurt by them specifically when we age and there is a threat that we are being laid off. My suggestion to all young people that are in their early careers is to ensure that they have a skill-set that is marketable regardless of age. That will keep them employed no matter what. This might seem a simple conclusion, but unfortunately I have seen too many to loose their jobs and struggling to get rehired.
