I find myself asking questions in the negative too, just like you and Jerry mention. Try this:

1. How can I be more grateful for the amazing friends and family I have?
2. What things make me feel the most fulfilled?
3. What have I experienced in my life that really makes me happy?
4. What are the 3 most important and meaningful things I can do today?
5. How can I learn to appreciate those who love me the most? How can I show that appreciation?
6. How do i make the most of my day?
7. What type of creative ideas are on my mind right now? How would I write them down?
8. What can I do to relax more regularly?
9. What type of content am I passionate about? What would I write about for free?
10. How can I act out love more in every aspect of my life?
