I think there is another thread like this, but I can't find it.
What are your thoughts in the morning (or in the afternoon) when you first wake up? Mine are usually Intuitive in nature. I don't think about my plans for the day or what I'm about to do. I always think, "Why did I wake up; and what is my purpose in life?" It's incredibly depressing sometimes. As the day goes on, I don't focus so much on these questions although they're still lingering in the back of my mind.
