Best practical training or book for expanding social circle?

I like to follow my interests, and join clubs, groups, or classes that pursue things I enjoy. Like a book club, writing group, church, etc. That way I meet people who are interested in the same things I am. What are your hobbies? What do you like to do? Is there something you want to learn how to do? You can look up local groups or classes on Google, and see if they have a Facebook page or are meeting online during social distancing. Getting to know people virtually first can make meeting in person easier. Finally, a classic book to check out is Dale Carnegie's "How to Win Friends and Influence People." Good luck!
