Happiness

Just got a random thought,
which one is important, your own happiness or everybody`s happiness?
Well, you probably would say, you can not make everybody happy
That is true.
You will only drain your energy just to make everyone happy.
but, does that mean, your own happiness is less important than others?
How are you supposed to live to the fullest if you are not happy at all?
Until what level, you can be happy without fearing of being considered as an egoist?

I do not know about another country`s culture
(although I think this will apply to in other countries),
but in my country, it seems everybody`s happiness is a priority
so if you do things that does not make everyone happy,
it will make you feel guilty about it
and some people would not hesitate to let you know about it.
Sometimes, you have to sacrifice your own happiness in order to make everyone`s happy.
Thus, everything will go smoothly for everyone.
At least, at the surface.

Some friends say to me, you only live once
Stop worrying whether people around you will be happy or not
with your choices,
just think about making your life happy,instead.
But, then, don`t you think it is quite selfish to do that?
how if your choice make others suffer?
or simply not happy?
is it totally your fault?
or is it their own problem?
