I think this also happens at the company level. You get good at delivering a certain type of solution using a set of technologies. You build excellent infrastructure and expertise using these, which is a strength!

However, without active effort to build capability in strategically important areas, your weaknesses can ruin you.

It works at the personal and company level. I’m the deep thinker/researcher type. At my age, that’s all for the good because you go up through the ranks until that’s a very valuable attribute. When I was younger though, I had to work hard on time-boxing and delivering the “good enough”; skills that are still vital when planning at the large scale.

The strengths and weaknesses are indeed two sides of the same coin.
