when is it too warm to knit a sweater?

i am working on my sweater again, yes this is boring i know. i need to stick a progress marker on it. this is a sleeve, talk about huge, but it doesn't look too bad folded over in half.

the color is darker in real life but i have horrible lighting conditions here and i was too lazy to put it on the window.

i'm not finding it quite as boring as i was, but maybe i am just too stressed to knit anything but stockinette.

i have had a horrible time concentrateing on studying. i get distracted so easily anymore. i also need to sleep more. i've created a habit of staying up until i can't keep my eyes open and i just feel more yucky every single day.
