Certainly everyone has hobbies, but why? We have to work for eating everyday, but if we have only work, our body and mind surely have a lot of stress.
We need some relaxation. We have dissolved our stress by hobbies unconsciously. By the way, how can we get our hobbies? Maybe it's correct that destiny control human life.
That is to say, it's destiny that we can get our favorite hobbies. It's a kind of a fateful encounter. I think that work is also same, that is to say, it's destiny.
But work and hobby are different. We can't live without work. If we lose jobs, our life will become unstable in our mind and body.
Of course we can live without hobbies, but if we can, we want to have hobbies. The most important thing is balance of work and relaxation. Some relaxation can give better work.
We need free time for work, and we can have hobbies in free time. Hobbies are important for us, because hobbies give us energy for work and life.
