Vision without action is a daydream. Action without vision is a nightmare.
– Japanese Proverb
Although it may seem quite obvious, I find this proverb to be smart precisely because of its simplicity. For me, this describes most days of a designer. You go through days where you have a clear vision about this or that project or even about yourself and your career, so you dream a lot and, most likely, you do not much. And, there are these other days where you just craft stuff out of your stomach. No process. No background. Just doing things.
