We are a small firm working for non-profit issues and campaigns. We
are writing a pamphlet and need some quotations/proverbs/sayings that
would apply to what we are trying to convey.
For example: Necessity: Necessity is the mother of invention"---Then
for our purposes "but in this case the impetus of creativity"
Creativity to think up your own catchy saying/phrase etc. is encouraged!

Catalyst: cause for the development of a new strategy, as in campaign
A had less money than campaign B so campaign A had to get creative in
developing new methods
