I also have found the trucker's hitch really useful from time to time. It allows you to tie down a load, for example a kayak on top of a car. You tie the initial hitch, and then you get to crank down on the hitch before tying the final knot. It's like a mini pulley system without a pulley.
The knot I use every day is a modified shoelace knot. You do an overhand, and then the first loop. Before you make the second loop though, you make two wraps around the first loop instead of just one [0]. Once I started using that knot, I don't think I ever had a shoelace come undone.
