to Hope or not to...

Hope create expectation,
and when you cannot have you expected,
it's leads to frustration,
I learned this along time ago,
when the moon was full,
give everything without wanting any,
it's easy to say and so hard to do,
and learned to let go all of things,
the only problems was,
How can I express it?
How can I make people understand?
How can I say it?
without making any regrets, anger and confusion,
the funny thing is that....
after letting go all the wishes,
I'm still hoping something,
that everything will be allright,
is that wrong?
