Specializing entirely in one area is a bit overrated. It's good to be competent in one or more things for sure, but there are surprising synergies / crossovers

Specializing entirely in one area is a bit overrated. It's good to be competent in one or more things for sure, but there are surprising synergies / crossovers between seemingly unrelated domains. The most successful people (CEOs, billionaires, political leaders, senior managers) are usually somewhat competent in many areas, rather than an expert in one thing to the exclusion of all others.
