Depends on situation...If we are making a debate and you say something which is your 'imagination', it is unacceptable, but if I am working on technical project creativity does matter, but the creative person should think whether his thought lies within realm of possibility or not...U_U
Because he was crushed by a rock and for Kishi to make such an obvious Obito character to actually be Obito when stated to be Madara, seemed kinda non-logical. I mean, I always thought he was just an old Madara, tbh, but then accepted he wasn't farther into the series. But I never would've guessed Obito. Then again, I don't care for most things, I just go with the flow of the manga, accepting everything given to me without arguing with Kishi.
I actually took a short test that told which part of the brain I use more; left brain (more logical), right brain (more creative). I came up as almost equal in both brains, but the left brain had the "advantage" by an extremely small margin. So if I had to answer from the facts; logic. But, I really don't take that test too seriously because I'm just as creative as I am logical (I play a couple instruments, I like to draw/paint, etc.).
well . it's good to have a balance between these two . if you over imagining it's crazy and can't be over logical . it would be like being a machine ( when working with someones feelings )
