Actually, all you have to do (this is my little secret technique):
Determine which two actions will cause a "negative" reaction (a loss in points.) Make sure you choose them when the smallest portion-thing is on them (therefore, resulting in the least amount of points taken away). Then, all you have left is points to gain!
If you're smart about it, you'll be able to get the smallest portion on both negative reactions, and then only gain points from there.
