The Pain Before Life

If there was no strife,
to counter - balance.
Then there'd be no life,
to reward your valiance.

It has to rain,
to get a rainbow.
There has to be pain,
before you can glow.

But being a pessimist,
can lead to disaster.
You have to be an optimist,
to live happily ever after.

So live happily before you die,
but remember: the cake is a lie...
