Knock yourself out

It's something unattainable
That you can't live without
And now the unexplainable
Has you riddled with doubt

Things begin Things decay

And you've gotta find a way
To be ok
But it you want to spend the day
Wond'ring what it's all about
Go and knock yourself out

Why were put in this mess
Is anybody's guess
It might be a test or it might not be anything
You need to worry about
But if you're still in doubt
Go and knock yourself out
