I believe it's important to keep a sense of humour in life. Although I might not always remember to, when I'm in an uncomfortable or stressful situation I try to look at it through a stranger's eyes and see what could be funny about it.
An example where this applies is... in math class.
I am definitely not a math person. I prefer english, history, and geography let's say, a thousand times more?
Despite the fact that I have an awesome-math-genius neighbor in my math class who helps me out whenever I don't understand something, I often am on the verge of a mental breakdown because I find math so. complicated. And most of the time I don't get just WHAT is the point of learning all these complex theorems and properties.
Anyway, I try to see the humour in those moments... I think the image above pretty much sums up what I look like in math class.
