I moved to Bali over 1 year ago, knowing only a single person in the entire island. Now I have dozens of good friends there. And a handful of them I consider really good friends with whom I have a good connection with and shared very intimate and vulnerable moments. These relationships keep growing overtime the more time we spend together.
Some friends I've met at the gym, others were my neighbors, others at BBQs, others at an acting class... The list goes on.
Maybe out of topic, but socializing is a skill. And it's sad some people associate socializing with = people pleaser. Learning to socialize is learning to engage with others and put yourself out there. Whether you do it staying true to yourself or not, that's another thing.
But going back to the main thing: Deep connections don't happen out of thin air, and not without effort.
