Better for you and your customers to tackle problems you have experience with. If you come from nowhere with no expertise in the sandbox you want to play in, you’re at a severe disadvantage because you cannot directly empathize with your customers out of the gate and need to spend that much more time on research to catch up. You’re behind before you begin.
What problems have you suffered in life and have educated theories strong enough to beat them? If you move forward without an underlying passion to solve a personal problem, what then will continue to fuel your fire? How can you possibly stay excited about an idea you have no emotional attachment to – a problem you do not understand?
I’m not telling you not to stretch yourself. And I’m definitely not telling you to skip the research altogether and go for what you know. Understand, however, that jumping into a business blind comes with much higher risk and a harder path to pave. One in ten million people get lucky building something they do not understand and making a business out of it. Press your luck to be the one or press your experience to build something you care about instead.
