bad brain day

a few days ago, i read an article about bad brain day. it's that moment when no matter how you push yourself to work,write, or do what you should be doing, you just can't. oftentimes we would say, just force yourself to do it. but the author said that it is sometimes more helpful if you just give yourself a break first, to allow the brain to recharge. if you cant run, then dont run. go home and watch tv. if you cant write, then dont write. this afternoon is my bad brain day. i have a literature review to write but i can't organize my thoughts. i have my notes but i can't write...well, academic stuff that is.
