Your logic stinks If nothing is going to be any different, my dear soothsayer, then why even bother wasting money on the drugs, much less more drugs?

While it is true there is "nothing new under the sun" you have not been under all your suns yet/before so you may feel it is all the same but it cannot yet be all the same to you. You cannot know what will happen tomorrow, who you might meet, what problems you might have or what gifts or solutions might present themselves to you. I like waking up (I'm 62) and wondering what might happen today, at least until about 4:30 in the afternoon? And, sometimes, I deliberately go do something or make something happen or discover something I didn't know but am now glad I did, etc.
