Read scripture. There are plenty of options for this depending on your beliefs. Whatever it is, allow this time for pondering, guidance, and inspiration for your life.
Plant a seed. Nourish it with water, sun, plant food, etc. and practice faith that it will grow. There is something healing in the practice of caring for a plant. I'm kind of a crazy flower/plant lady myself but it definitely makes me happy.
Positive Mental Rehearsal. Maybe you're someone who currently has a lot of faith in a higher power but are lacking in faith in yourself. Consider practicing positive mental rehearsal this week. Write out all of your good traits, skills, and attributes and read through them every day. Add to the list as you think of others. You are unique, special, and have a purpose. Hopefully this practice will help you see that!
