It’s all about using “little bets” and seeing how the market responds.
The key to this approach is having the right attitude toward failure. You can’t be afraid of losing, but rather you have to see failure as a learning opportunity. Fail quickly to learn fast—it’s not a natural mindset, in a culture where we are rarely rewarded for failure! But the faster you fail, the better, because you get feedback from customers and opportunities to reinvent and improve, to create a product or service that works.
To succeed, keep making lots of little bets. Try new things. Be curious, and take risks. You never know what might work—and what might give you the inspiration you need.
