I think consistency is more important than number of events. Building relationships with people will gain you more momentum than meeting 100 new people who likely won’t remember you and you can’t actively get to know and build rapport with. Choose A couple groups that meet on a monthly or bi-monthly basis and be consistent and care about the people you meet. Make it about them and not you. And when you leave, actively look for ways to send them referrals too otherwise you are just another business card collected and forgotten.
