1. Join easy access associations.
2. Join a church, or a bible study
4. join a crossfit, camp gladiator, or other small group exercise group or gym.
I never said it would be easy. I recommend college alumni groups, reading groups, meetup groups, and a exercise related group. Why because college alumni will have massive network opportunites, exercise related groups will keep your body in check, and meetup groups have a wide range. People get mad at me when i said join a church. Why because folks love to buck authority thats fine. I enjoy joinging a church because I love the lord, will be surrounded by other folks who love the lord, and they have groups for different life stages, singles, married, divorced, and new believers, etc.. Within two years of moving to a new city I have expanded into a 500 person deep network. Now yes i am a high energy, extrovert who loves having something to do every night of the week, but dont let being a introvert stop you. I will go more in depth on this topic soon.
