Most quotes in business presentations are cheesy cliches uttered by people you never heard of. What can you do to avoid falling in this trap?
Decide whether your story actually needs a quote at all. In many cases the answer might be “not really”. That workplan deck for a major cost cutting project does not get any more cheerful with a happy “let’s do this together” quote at the end.
If you want to give it it a try, make the quote very specific to your situation. Googling “inspirational business quote” will definitely not get you a specific phrase. Generic inspirational quotes have been used so much that they might actually have the opposite effect of firing up people to do something passionately. Quotes with a touch of humor or self-mockery could work much better.
To weed out the business book best seller authors, search for quotes by specific people, either because they are in a relevant field or maybe because you admire them. Oscar Wilde produced many for example.
Make sure you get the exact, correct, original version of the quote by doing a bit more research than the first Google result
