Outgrow

That which you can't abide,
embrace as if a friend.
Once you two have allied,
nothing will make you bend.

That which you can't escape,
welcome as a teacher.
You will never expose a more talented lover.

That which you won't challenge,
can't ever make you wise.
But that which you surpass,
in freedom makes you rise.

That which you merely change,
comes back in a new disguise.
But that which you outgrow,
Won't again meet your eyes. =)
