Keeping all your stats, abilities, feats, gear, and spells straight for your character is very important. You might forget that you have that one ability that would totally make that fight super-simple if you just remembered it. Having a good, clean, and organized character sheet will help with that. And Paizo is taking pre-orders for their Pathfinder 2nd edition character sheet pack now.
