We all have different hobbies. What is one hobby that sets you apart from your friends and also has a constructive usage.
Mine is to learn how to code in various languages by accepting jobs. That makes me work better under pressure of submitting my work fast.
P.S: Making memes doesn't count.
I hope I have collected all old currencies from 1900 and I also have some gold coins minted by Kings.
Apart from that I read a lot of stories in my native language which relaxes mind after a long day of work
