write more letters by hand

I’ve actually gathered all my envelopes and stationary into a folder, but now my problem is—whom should I write to?
I know it should be about ME writing letters by hand, but I just have this feeling nobody would reply to me, because e-mails are the way of the world today… :( I don’t want to keep writing into the air, not receiving any replies, do I?
I miss those teenage days when I had so many penpals; at some point even 22 at the same time!!
