Get out and meet new people and learn new things!

Don't go to your local "I want to build a startup!" meetup as those are almost always useless. 99% of the people there have an idea and "just need someone to build it!"

Instead, check out events, meetups, conferences, trainings outside your core field. I went to a few game developer events and then music+tech meetups and learned a bunch but the most valuable were construction technology. Project management is project management. Accounting is accounting. The industry/situation changes some of the specifics but it's many of the same principles and concepts.

The vast majority are free, you just have to show up.
