Some words of wisdom from Mother Theresa. She is desribing what it means to be "holy":

To be holy, doesn't mean to do extraordinary things,

    to understand big things,

But it is a simple acceptance, because I have given myself to God,

    because I belong to Him --

            My total surrender.

He could put me here.

    He could put me there.

    He can use me.

    He can not use me.

It doesn't matter

    because I belong so totally to Him

    that He can do just what He wants to do
