Some personal questions that just popped in my mind.
What is the root cause of my emotions and what can I do about it?
What is it that I desire?
What is it that I'm grateful for?
How can I make myself feel happy and stay there?
What values do I hold dear?
Why did I get up from the bed today?
How can I become better?
Am I becoming better from this?
How does this person makes me feel?
How do I make that person feel?
How are my friends?
and the list goes on :)
