When I started my career 30 years ago, people graduated with a single-mindedness that saw them end up in companies (sometimes the same one for their entire career) and work until age 65 when they could finally gain their freedom. Things were relatively stable with no switching path in mid stream or taking sabbatical breaks.
Today things are different, and with more uncertain expectations about career choices, these young people are staying in school longer or conversely graduating and going it alone with homespun businesses rather than opt for a large firm which no longer guarantees gainful employment.
When my son and the doctor decided it might be best for him to take a medical leave, my heart skipped a beat because I was used to the idea of just getting on with things. But then I think about the safe choices I made and realize that isn't necessarily the right way to go. Being true to yourself in every way while finding some compromise to make a living is what I favor today. However, I made my choices and am left with the idea of rebranding myself late in life so I can live more honestly going forward.
I would rather see my kids be more fulfilled in their profession than I was and, while I have no major regrets, I know I am a victim of the "this is the way your life is" school of thought.
