Give them a rating ranging from 1 as bad to 5 as good. You can also add a sentence of judgment. Below is an example from an anonymous group of people.
Example:
John: I got to bed at 10 pm and wake up at 5 am.
Sam: 5/5, good job, you get your 8 hours of your mandatory sleep! I go to sleep at 3 am and wake up at 6 am.
Josh: 1/5, you need to sleep more. See I'm perfect, I sleep at 5 am and wake up at 6 am. HYPOCRITE!
Let's get started!
On average, I go to sleep at 9 pm and wake up at 5:50 am; I get tired easily during the day.
