There are wise and wonderful poems about being open to possibility and change.
The following Holub’s simple piece of ‘The Door’ poem asks us only to take a chance, to go and see what might be there if we take small first step.

Go and open the door.
Maybe outside there’s
a tree, or a wood,
a garden,
or a magic city.
Go and open the door.
Maybe a dog’s rummaging.
Maybe you’ll see a face,
or an eye,
or the picture
of a picture.
Go and open the door.
If there’s a fog
it will clear.
Go and open the door.
Even if there’s only
the darkness ticking,
even if there’s only
the hollow wind,
even if
nothing
is there,
go and open the door.
At least
there’ll be
a draught.
