> ...don't have enough time to really be immersive in anything

I understand you're running a company and on an absolute basis your time is limited. That said, all of us are guilty of "never having any time" when really it should be described as never making time. You have to get over the concept of being too busy for everything else and actually make time for something you want to do.

If that means learning some mathematical problem, schedule an hour at night to sit at home (or location of choosing), ignore your email/Slack/etc., and learn. If instead it involves meeting people, go to networking events, introduce yourself to people, and generally go out of your way to be active. Just MAKE the time, don't complain about not having it.

For what it's worth, intramural sports teams are an effective way to meet people if it seems impossible. Also, Meetup/etc. groups for something related to a shared passion (e.g. photography).
