My suggestion is to look at everything through the lens of "how can I make this better?"...from that angle, suddenly the world starts looking like one, massive, un-tapped opportunity. When you hit on something you're passionate about do a deep-dive on the market and you'll find people who will want it (it's just about refining in what form and at what price). The reason you'll need to be passionate is that sometimes people don't know what they want until they see it - it takes passion to drive demand :)
