I practice withdrawing into myself. It's kind of a Stoic exercise. Go within. Ignore all external things beyond one's control. I can go for days & never see or speak to anyone.
I don't meditate. I do what I want. I read or watch films or study a subject, usually philosophy or religion. But I have little to no human interaction. Most people are so shallow & vapid, they are not worth my time. They're a drag. I'd rather be alone.
