Trick Your Mind Into Working Mode
The reason why I add wear something that you associate with working is because when I am wearing pajamas I feel sleepy being that I have associated this type of clothing with resting and sleeping. However, when I wear comfortable clothing such as working out clothes, which I have associated with working, I feel less tired and more focused on doing something. Therefore I suggest you wear what you would use to workout, but don’t sacrifice comfort.
Another thing is I get ice cold water to drink. It will definitely energize you. I wouldn’t suggest eating before doing the assignment, because 15 mins after I eat I need a nap (Lol). If you need a snack eat almonds(If allergic to nuts then eat a fruit) they are good for your brain and won’t make you feel sleepy after eating them.
I also use piano music, but I mostly use beta brain waves. You can use any music that does not make you feel sleepy or has any lyrics in it, as it will distract you.
