It is sunnah to start your day saying:
اللهم إني أسألك خير هذا اليوم وخير ما فيه وخير ما بعده، وأعوذ بك من شر هذا اليوم وشر ما فيه وشر ما بعده.
O Allah, I ask You for the goodness of this day, the goodness within it, and the goodness that comes after it. And I seek refuge in You from the evil of this day, the evil within it, and the evil that comes after it.
