The difference between good design and great design is time.
“Great design takes A LOT OF TIME. Great design doesnâ€™t just happen. Itâ€™s the result of research, planning, and iteration after iteration. Itâ€™s not your fault you donâ€™t know that â€“ as you go through your life, you only see the finished products. You donâ€™t see the months of work that led up it”.
