What tips have you found to improve your mouse movement and control?

I've been a long time casual PC gamer. However, despite considering myself average/slightly above average in the things I do play (CS hsmod deathmatches, OW, PUBG) I feel that there's something fundamentally wrong with what I'm doing, rendering my control lesser than other people particularly in making fine adjustments)

First and foremost, I can never seem to have a consistent grip. My hands get a little sweaty and I let my grip slacken, so it usually ends up with me loosely holding the mouse and just nudging it about, it works but it's imprecise. I own a G303 and whilst this mouse is slightly more accommodating for that style of play than certain others, it's not ideal. When I'm consciously gripping it more tight my control is a little better though. I've been playing with the Ninox venator too and if I death grip it with my thumb, I can play pretty well, but it absolutely kills my wrist through the strain of gripping it so tight. So I can get a match in before my wrist feels like it's going to fall off.

I'm always switching between grips on my G303, from one which grips the mouse with the top half of my hand (fingers) and leveraging my thumb on the curve for support or a claw grip (which I find difficult to maintain). The claw grip is generally more precise but more difficult to maintain and need a higher sens, less ability to make sweeping motions with accuracy for me.

I've owned so many mice in the past it's ridiculous yet I've still never found one that fitted me like a glove. I feel like there's one out there for me but none of those on the market fit me, I certainly think I prefer mice with forward sensor positions since I use my fingers for fine movements a lot. I have above averaged sized hands, but equally I'm not sure if bigger would be of any help.

Also I think my monitor is too close and since I have intermittent exotropia (left eye is a little favoured by my brain) it doesn't help with the eyes working together. I should move it further back but desk is too small haha. My visibility is pretty poor, once I can see the target I'm usually pretty good. I also feel that my eyes respond well to an increase in hz/decrease in blur like with lightboost, I do have a 144hz monitor but I hear there's 240hz ones out there now.

Posture, chair height and arm positioning are also things I'm not 100% on. My chair is the highest it goes but I'm not sure it necessarily helps having it this high since resting my arm on the table is less natural.

Of course there is such a thing as natural ability and that's fine with me. I just want to maximise my own potential. So, what are your tips for improving mouse movement and control? '); }
