I agree with Rick's statements. I also think that during the learning stages of being a designer.... actually imho we should never be completely out of the learning stages but I guess I mean early on.... it's good to "polish a turd" from time to time. You learn a lot that way. I was fortunate enough to be raised by great teachers, one of which was actually a school teacher for a long time. I have found that part of the process of getting better at your trade is learning from mistakes. I don't think they ever once told me to completely scrap an idea and start over from scratch, even if that was probably the right thing to do. They tried to teach me how to improve my own creations and I felt like that helped me progress the most. The end result of polishing a turd isn't usually a great design, but it's not a total waste of time either. Over time you will learn that what usually makes those turds, and the reason why they are rarely transformed into a delicious cupcake, is the lack of basic design principals.
I agree that at some point, polishing a turd is
like scratching that itch... or uncovering the good
idea that might be lurking behind... it must be done
sometimes.
I also say design the bad ideas, that way you get them
out of the way to make way for the good idea.
But before polishing anything, research, learn the visual
language, start drawing, then you can see where that
takes you...
I was going to show the OP an old thread but it's in the
premium section. I might as well show it as an example
of drawing out rapid doodles, then polishing them... some
are baaaad, but the idea is to learn to visualize at a fast pace.
