Recite Invictus and remain steadfast in your own sphere of control. Go out, do the best of your ability and those are the only things you can do.
Be accepting and open when things go your way and remain calm if they don't just yet.
The Invictus Poem if interested.
From out of the night that covers me Black as the pit from pole to pole I thank whatever gods maybe For my unconquerable soul
In the fell clutch of circumstance I have not winced nor cried aloud Under the bludgeoning of fate My head is bloody but unbowed
Beyond this place of wrath and tears Looms but the Horror of the shade And yet the menace of the years Finds and shall find me unafraid
It matters not how strait the gait How charged with punishments the scroll I am the master of my fate I am the captain of my soul
