From "Finding Your Work Sweet Spot: Genuine Interest, Skills & Opportunity" by Scott Belsky (emphasis mine).
As you contemplate your next career move or a new project, you should take the intersection of your genuine interests, skills, and opportunities into consideration.
Contemplate the three circles of the Venn diagram above – one circle encompasses your genuine interests; one, your skills; and one, the stream of opportunities available to you. An intersection between just two of the circles doesn’t cut it. A love for basketball and a connection to an NBA scout won’t help you if you lack the skills to play ball. You need to find YOUR trifecta. When you engage with a project that finds this intersection, you’ve entered your zone of maximum impact. In such a state, you are a potent force of nature – your avocation becomes your vocation. You can work with full conviction, without ambiguity, and you can transcend your reliance on short-term rewards and societal approval.
As leaders, we must help our partners and employees find work at the ISO intersection. Legendary managers seek to understand the genuine interests and skills of their employees, and are constantly trying to create opportunities within the intersection. Want to change the world? Push everyone you know to work within their intersection. Mentor people to realize their genuine interests, skills, and to capitalize on even the smallest opportunities that surround them. When it comes to your own career, make every decision with a constant eye for work in the intersection.
