Good design executes on the possible.
Bad design ships on time.
Great design reaches for the implausible.

Good design has only the parts it needs.
Bad design is cluttered.
Great design has fewer parts than seem possible.

Good design doesn’t fail.
Bad design fails a lot.
Great design fails even more.

I have done good design.
I have done plenty of bad design.
I always want to do great design.
