How Much?

Among two of the first decisions I need to make each day are are what size oatmeal bowl and how much mix-in.  Clearly, how much is a personal decision.. like how much sugar, if any, to put in coffee.  But, unlike coffee where someone often adheres to none, one or two teaspoons.. I find that how much oatmeal mix-in varies with the day.  A little sweeter yesterday.. less sweet today. It's an on-the-spot decision that's important to get my day off to the right start.
