Have you seen the calendars that have the date and a message for each day in them? I happen to have one on my desk (given to me by one of my good friends when he left the country) and today it reads "After a point in time, people will not remember how fast you did something, but they will remember how well you did it"
I just want to ask the person who wrote it if he ever worked in a job that had tight deadlines. Then he might know the importance of doing something fast. I agree doing something well is very important but in a lot of occasions, doing something fast is also translated as doing something well. I sometimes get real mad at people who do things well very slowly as i really think your speed to a certain extent reflects your expertise.
I guess it is all about morphing according to the needs of time.
