As a DM, I have to roll a lot of dice in-game. This takes time, which is a precious commodity in the midst of a heated battle.
So I printed up a list of over 100 die rolls for a d20, and pulled that sheet out at the beginning of every session. Every time I need a die roll, I look at the next one on the sheet and cross it off. Once I realized how useful (and fast!) this is, I added d10, d8, and d6 die rolls to the sheet.
This is so useful that I'm now sharing my die roll sheet. These are random numbers, which I further tweaked to remove long sequences of low or high numbers.
