I used to be able to wake up very early in the morning and be in the best, chirpy mood. But not so anymore. Waking up early feels like trying to un-superglue myself from bed. I am most productive/inspired after midnight. It's very quiet and breezy and serene.
Haha I was as well. Always got up at 3 am to do work before I had to be at practice at 5 am. Now if I get up before 8 it feels like I have a hangover the entire day, irregardless of how much caffeine I put into my body.
If I need to get stuff done, I'm most productive around 6AM-12PM-- less noise, less distractions, less temptations, plus a rebooted mind cleared of any temporary internet files from the day before. Plus, sometimes it is just best to just sleep on a problem, let it soak in overnight, and let the brain do the heavy lifting for you.
