Tips for improving aim

So,I am trying to improve my aim but I feel like my aim is getting worse and worse as time goes on.And now I am at that stage in which any kind of tip will be appreciated

Quit the game for 2 weeks and come back and ur aim will be better

If you play worse and worse the best thing to do is take a couple of days off for that mental reset. If you want to aim train then grinding the shit out of death matches is probably the best option

Work on crosshair placement and lower your sens so you can have a better control of it and maybe try some scenarios on aimlabs for flicking and tracking

take a few days off comp or even the game in general. i dm an hour a day and play 1 comp a day... helps me

you need experience. you wont get good aim overnight
