TL; DR
Innovators often mistake everyday "frictions"–things that are annoying or limit us somehow–for "problems" that users are motivated to solve.
The key difference: a problem is a friction that people are already trying to fix. If users aren’t taking action, you’re likely chasing a friction, not a real problem. In that case, people may just see it as an everyday part of life; annoying maybe, but not a priority.
To build products that matter, look for evidence that users are already hacking together solutions or making sacrifices to overcome an issue.
