When today you have doubts and fears, why not follow the advice in this Mary Oliver poem. To look at nature all around you –  the buds beginning to appear, the early flowers blooming – and see there a support for your inner self.

Oh, my dear heart,
My own dear heart,
Full of hesitations,
Questions, choice of directions,

Look at the world.
Behold the morning glory,
the meanest flower,
the ragweed, the thistle.
Look at the grass.

Mary Oliver, The Singular and Cheerful Life
