Do you want to feel happy?

　First of all, you should take your work easy. It means "Let's put
you at ease." If you maintain stability, you'll be happy and able to
have a good result. Second, you should find something which you
have interest. If you enjoy your work, you'll get rid of stress.
Even if something you should spend much time and efforts, if you
are interested in your work, you could feel happy. These days,
many people suffer from mental stress, and I think it is serious
problem. As you know, stress gives rise many kinds of diseases
and even it leads people to commit suicide. Because of this
reason, first of all it is good for you to enjoy your work, but we
can't be always happy, so you need to have your way to free
your stress.
