The trick to achieving contentment

I think the trick to achieving
Some kind of contentment
With life
Is to not place conditions
On your happiness.

If you can be content
With a life that may not meet
All your prior expectations
Then you have a chance
Of happiness.

If you require your life
Or the world, more generally,
To achieve a certain outcome
Before you decide
Life is worth living
Then I think you will be disappointed
And may give up hope entirely!
