Some examples of people quickly accomplishing ambitious things in the shortest time.

Constraints foster creativity (if the right people are in the team). When JFK announced (in 1961) USA’s intention to put a man on the moon before the end of the decade, he set a time constraint that could not be moved without considerable global embarassment. In less than 9 years, it was accomplished. Perhaps the formula is: a deadline + right people + leadership support.
