Alright, I've been thinking. When life gives you lemons, don't make lemonade - make life take the lemons back! Get mad! I don't want your damn lemons, what am I supposed to do with these? Demand to see life's manager. Make life rue the day it thought it could give Cave Johnson lemons. Do you know who I am? I'm the man who's gonna burn your house down! With the lemons. I'm going to to get my engineers to invent a combustible lemon that burns your house down!
Ignore the dog and focus on the lemon tree.
– Cave Johnson, Portal 2
Don’t get turned off by the fact that this quote comes from a fictional character and from a PC game nonetheless. This quote actually has a lot of meaning to it.
The old adage we’ve heard or been taught by our parents was that when life gives you lemons, make lemonade (this is usually follwed by an exclamation mark to show the enthusiasm!). In layman terms, this means: take what life gives you and make the best out of it.
