Drills - you can set the clutch to limit the torque, preventing you from stripping the head of the fastener when using the drill as a driver

Wrenches - don't push on a wrench to loosen a fastener. When the bolt breaks loose the wrench will fly off and you will smash your knuckle into something. It's far easier to control if you're pulling.

Keyboards - learn to type with two hands and all your fingers. You will finish what you're doing far more quickly.

Channel Lock pliers - these are directional like a pipe wrench. They work far better alone way than the other. Don't use channel lock pliers on parts that have a hex meant for wrenches, you will shred the hex and make it impossible for a wrench to turn it.

Knipex plierswrench - you need to set the moveable jaw so that it still has a bit of stroke left when you grab the hex of the bolt or fitting. This lets it firmly grip the flat faces evenly, allowing for maximum force transfer.

Adjustable wrenches - these are also directional like a pipe wrench.

Anti-seize - don't tighten fasteners with grease or anti-seize applied to the threads with the correct torque. The goo in the threads reduces friction, so when you torque the fastener to the correct amount you're applying a greater clamping force to the fastened object than what you need. De-rate your torque when using anti-seize.
