Nate Tilley says maxing out your mouse pointer speed can roughly double your efficiency. It takes a few days to adjust, but the faster navigation compounds with other small optimizations into real productivity gains.
Increase the mouse pointer speed/drag the mouse speed setting to the maximum (full).
If I go and I sit next to somebody and I see how they use their computer, I need to do one thing to improve their efficiency by double, and it's typically getting their mouse speed and dragging it up to full. Like, either I can see someone's got their mouse speed at 50%. It's just like, oh, my God. Like, you poor child. What have you been doing? Let me show you the way. Right? That's the way that you're going to be using your main piece of machinery to do your work and navigating around that. So it only makes sense if you can navigate around it quicker. You're going to get more output, and it does take some while to get used to. But it's these little speed improvements and these micro optimizations that give you a lot of efficiency when it comes to tools.
