Never knew this even after years of using a computer MOUSE CALIBRATION:

You should actually do this every year. Even more often if you spend a lot of time on the computer. I was shocked to see how well this works, and how far off mine was!

To re-calibrate your mouse, place your curser on the capital H below, left click and hold, then drag it toward the small g.

If it doesn’t work immediately, you might want to clean your mouse, as the calibration is off.

H o l y S h i t!!! You’ll believe anything

I’M SURE YOU WILL ALSO RECOMMEND THIS TO ALL YOUR FRIENDS ONCE YOU SEE HOW MUCH SMOOTHER AND BETTER THE MOUSE WORKS AFTER BEING CALIBRATED!
