i deliver groceries for an app for work rn cause i'm in school and it's decent

but because it's the modern gig economy hellscape, the way they evaluate you is letting customers rate how you did. it's a bullshit system cause you can't really control a lot of it -- like what orders you take, how well stocked stores are, them being dumbasses, etc. it's also a bullshit system because anything less than 5 stars is considered failure. out of 5. 

your average rating determines, overall, if you get fired or not if it gets too low. they've also decided that if it goes below 4.7 out of 5 (4.7, the number which is basically 5) you basically get worse jobs to do. 

it always fluctuates up and down because there's no real way to control it. the subs about it are toxic af because some people totally buy into it. 

it never really truly affects my income - i have the concrete numbers to look at and it truly doesn't.

it just makes me feel shitty about myself despite actively trying to not care. 

how can i stop caring?
