At school, I started with a 750 ml bottle of water, but later I lost it at the bank. Next, I carried a 350 ml bottle.
Thing is, even though the size of my bottle changed, I continued to drink the same number of bottles each day, roughly one per class. So changing the size of my bottle radically changed the amount of water I drank each day.
I’m not sure how this applies to anything else (yet), but there’s a lesson in it somewhere. Perhaps you can find it.
