The best advice I can give us to build something for pain you feel. Maybe it's edtech integrations or a part of your workflow or life that needs optimization.
If you build something for other people, you'll need user discovery and project management skills up the wazoo if you don't have a team with that expertise. And you're at risk of building Facebook for Cat Owners or something like that. Start with your own pain until you have more experience transforming user pain into something they'll pay for.
