what's the most important thing you've learned In life

I know a lot of things.
I know that at night, the shadow of the door
on the roof,
can either look like Patrick Star,
or the grim reaper.
Take your pick.

I also know that if you’re loud enough,
you can be quiet enough when you disappear,
and no one knows where you are.
Or maybe they’re so annoyed with you,
that they don’t care.

I know that if you look in the mirror too long,
you'll find yourself turning from side-to-side,
rating every part of your body out of ten,
and you will find that you
hardly ever get higher than a seven.

I know that if you bury yourself
deep enough in something,
the rest of the world will hurt less.
But a forewarning-
This doesn’t always work,
sometimes it hurts more.

I know that if you have a good enough poker face,
Blackjack is actually pretty easy
(when you aren't playing against your father).
And I also know that poker faces
are more important than you might think.

I know that if your throat gets a lump,
you can swallow it down,
but once your nose starts to tingle,
9 times out of 10, you’re going to cry,
and you won't look pretty while you do it.

I know that if you close your eyes,
you can wish away a lot of things,
and make up a lot of things,
but when you open your eyes,
your wishes didn’t come true,
and your dreams aren’t real.

I know if you give someone a part of yourself,
and they leave you,
you’ll spend the rest of your life
trying to get it back
but you never will.

I know a lot of things.

Without certainty you cannot begin
Foundations always moving are not
For on such you can never build
But only to be moved and carried
Endlessly without rest always changed
Discarding the old attempting the new
But waste and futility, no mastery nor success
What knowledge gleaned very soon irrelevant
Here today, everything's changed tomorrow
Always a toddler, crippled for life
To stand for a while the pinnacle
To walk or run, foolishness, for falls
And you break, never crawling again
But for grace the sand steady as a rock
That you may know sand shift in winds
And to search for rock before you build
But not boast the death of certainty

When do you know
you're growing wise?
When you feel
you know far less.

The lion hides behind the truth,
A gallant knight on pain of sword.
The blind man sees which way to go,
A beggar finds his just reward.

A babblers tounge will never cease,
The tin man masks a heart of gold.
A compass always pointing north,
an unloved heart is treasure sold.

The castle strong as weakest point,
The truth will always stay the same.
A lonesome clock has all the time,
How can mortal man give God a name?
