Going by the way something seems and not what's actually possible. Unable to see what is right in front of you because of pre-existing thoughts or ideas you may have. 2Pac used this word a lot.
Perhaps I was blind to the facts, stabbed in the back/
and in my mind I'm a blind man doin time/
we took a minus, and now the hard times are behind us, turned to a plus, now we stuck, livin blinded/ - 2Pac
