You Are Intense Yet Happy
You are a pretty tightly wound person. You can be extremely passionate and dedicated.
And while you definitely have a lot of intensity, you don't take yourself too seriously. You still have a good time.
Whoever first said "Work hard - play hard" was thinking of someone exactly like you. That's pretty much your personal motto.
You never do anything half way. You always go full force - whether you're working or having fun.
