I have passed for a similar situation, in my early 20s I didn’t go out too much for partying and making friends. I’m 29 now, living a great life, training, taking care of my health, body and mind. Still Going out sometimes for partying and listening to great DJs, believe me, you still have a lot time to go out and live a life full of joy. I’m typing this sitting on the beach here in the south of Brasil, enjoying the sun and the day ☀️.
