Exactly this. It's about finding a balance: know enough about a specific topic that you're a go-to person ("an expert") and enough about other topics to understand the context and opportunities for your area of expertise. Too much focus and you can't see the forest for the trees. Too much general knowledge and you're a jack of all trades, master of none. Finally, note that "balance" is subjective. It's the balance that works for you and where you want to go. Deep, focused experts are valued. Generalists are valued. Find your niche.
