Can'T Stop Thinking

My brain is on constant overdrive and it won't leave me alone. Thinking, thinking, thinking about random bull every second of the day. Like whether I can weather the weather... How exactly will I die? Don't get me started about late night, wide-eyed, crooked arm behind-the-head, ceiling-staring thinking myself in circles. Probably why my thoughts have little to no point; it's even worse when I'm stoned. Oil is produced from dinosaur bones and gelatin is made from animal bones. So can my niece power her school bus with her packed lunch? I think about past mistakes, but what use is thinking about them if I can't change a thing? Sleep overtakes me as I think about what thinking means...
