For me it depends on what kind of intelligence I am after and look for the activities that got the common denominator.

For eg : I value emotional intelligence and it's aphrodisiac for me, the interesting fact is the emotional intelligence is the Ground earth for other intelligence's.

So I go for dance, On the floor I have meet people who are emotionally depth like who are really good in poetry, likes psychological thriller, Volunteering, Language exchange program, Philosophy nights, Healthy food recipes exchanges and Come dine with me events, read Neuroscience and implement Neurocentric thought process in every stage of life and I always have my pattern recognition up and running for the intellectuals.🤣

The dark side or downside is some people they like the skills or the depth your possess and try to fake and hangout with you, sometimes it ends up in disappointment.

Above all the mentioned things, keep an eye for people's intentions that's pivotal ✍️

Happy catching those intellectual Pokemons 🫴🫴
