A Bloomberg article was recently posted that despairs working age people foregoing having children to focus on their careers in significant numbers. My perspective on this topic, having 2 kids and a 20 year professional career, has gotten more nuanced over the past few years. Your career is worth investing in to point that it will allow you to have a stable and satisfying life. Treat your career as a game to be won with the biggest high score at your own risk. My longest tenure at any one company has been 6 years, and many previous projects I was proud to have worked on no longer exist. In many cases the entire company no longer exists.
Things in my life that have lasted significantly longer than 6 years:
Your career is important, but it is more transient than you realize, and you have less control over it than you’d like. Prioritize the things in your life that cannot be taken away by a reorg, and will be measured in decades.
