Let's think together (1)

Am I being the one confusing whether it's white or black?
This thought came up upon what I've read in a book. I can't recall what book it is. Please tell me if you know. According to it,
You will be said you're still immature if you say what is black & what is white. Then you try yourself to change and you get able to say " Wow..it's not black.. just grey .. a little white" " Wow.. not white too much" . Then you're said you're getting mature & wiser. Then you can't even define what's white & what's black.
I ever think I'm a sociable person.
I ever think I'm a positive viewer.
But at the same time I never think I'm decisive. Moreover, I'm wondering if I'm being the one confusing black & white. How about you? Don't be like me!!!
