A to Z

Something is just like ABC,
it starts from A to Z.

I climb too fast, reach to Z very early,
while other still climbing.
I wait too long for them to reach.
Then I just relax.

After relax,
meet up all the climbers.
They ask me, "Do you have the map while you climb up from A to Z?"
I dint realize,
I climb too fast,
until I forget to mark down the way while climbing from A to Z.

At the end, I have to jump down from Z to A.
And climb back all the way up to Z again.
What to do?So much of efforts,
but did it in a wrong way.

Stand up from where we fall...
