When I have something to wake up for, such as school, I'm definitely an early riser. However my peak hours are generally at night, since I'm able to focus on the things I care about w/o distractions!
it depends lmfao sometimes i sleep at 3 am and wake up at 8 am or i sleep at 1 am and wake up at 11 am. my peak tho? probably later on like around evening because im generally low energy so evening is my favourite and most chill time
