What's the hardest part about blazing a trail in your industry?

I'm interested to hear what everyone has to say about this! Especially in tech, the world and people's needs are constantly changing. This means that the products we're creating have to change with it, and the most successful products tell people what they need before they know they need it. As exciting as this is, it's super hard too. Reaching out to fellow trailblazers: what do you think about this? What are some of the tradeoffs?
