Hobby can turn to business

Hobby comes in many diffrence ways. Some hobby are very expensive to follows, while some have no value but the beautiful of collecting it and some will have the value in the future. My hobby is collecting first days cover when I was very young but stop it as I can't affort to buy when a news covers comes out.

I have a friend of mine who likes to keeps junks things as a hobby when he was young. He would travelled with his bike to collect old clock and things which he thing worth to keep. His busy days is always near chinese new year when people start to throw unuse and old things. Now he is owning a antique shop and a junks shop.
