You know, you can pull a card from your tarot deck and allow that to be your focus. You don't have to pull blindly; you can intentionally pull certain cards to bring that energy into your life.
If you're looking for more optimism, positive energy, and luck, for example, you can pull the Sun from the deck as your card of the day. Meditate on what it means to you and how you can see/bring more light into your life.
What card would you use to focus your energy today?
