It's Great To Gain

You really don't want to use the Wishing Powder yet, but it seems to be calling your name. You take off your head phones and walk over and take the Wishing Powder from behind the picture frame and hold it in your hands. You start to wonder if you really should use it. You quickly decide you will use it and if you get too big you can always wish yourself smaller when you go to work.
You look on the label of the Wishing Powder and the instructions read:

To use the Wishing Powder: mix a small amount of powder into liquid, stir, and take a sip and either say or think your wish.

Sounds easy enough, You think. You head downstairs to the kitchen and take a glass and fill it with water, then you take a spoon and take some powder from the bottle and stir it into the glass. You head back upstairs with the green looking drink and head into your room and sit down on your computer chair.



What should you wish for?
