I agree with you SM.
Defining happiness is subjective and it may be different from each
other. Some may even try so hard to get their desired happiness.
My opinion is that we should be happy whatever the situation may be.It
doesn't mean we should do nothing but content our life.We must try to
be happy even in the time of pursuing happiness.If not, too much happy
time has been wasted to get a certain kind happiness.
It may be difficult to practice in reality. Anyhow, life is short, we
must value our precious life. So, be happy anytime.
