Exercising the imagination can be scary, true, but this "out of the box thinking" is extremely edifying. The cliche is almost laughable because "thinking outside the box" is basically asking you to solve a cliche problem with a cliche! BUT, wouldn't it be wonderful if you lived in a space where you never got "boxed in" in the first place? Where you lived in the space OUTSIDE the box? Not the BLACK and WHITE, but the place where all the other colors reside.
Hiding in the crowd and "playing along" is safe, but is it satisfying? There is an artist inside you, and you deserve that self-exploration. Don't let the fear of others-thoughts get in the way. Pippi sure didn't think twice about what the perceptions of others in her journey; and that mindset served her very well! We could stand to learn a thing or two from the girl!
