I actually have three:

“I have no special talent. I am only passionately curious,” – Albert Einstein

"It is hard to teach a coder how to think, but trivial to teach a thinker how to code." – Unattributed

Both of the above quotes cater to my autodidact self in more ways than one.

"I reject your reality and substitute my own" – Adam Savage, MythBusters

This one is as just funny and witty as its author and often holds true in my day-to-day life.
