1. What’s the best hobby anyone could have? To be able to have it by anyone, it has to cost a minimum or it doesn't cost money. There seem to be many good applications on mobile phones these days. There are many program for Stretching or exercising that looks at the cell phone screen and we can follow it without the help of special instrument or teaching coaches. I've done it before, and it's very useful. However, it is not always easy to sustain a hobby that one does alone. 2. Why should/shouldn’t we have hobbies? Hobbies can't be everything in my life. However, when I do work for my life, my hobby gives me motivation to work harder and gives me wisdom to solve the problems when I meet difficult things. And knowing another world can make my life richer.
