Looking for a Quotation help please

I'm trying to get use a quotation for a presentation, and for the life of me I can't remember exactly how it goes,or who the author is!

To paraphrase the sentiments:
*
Don't be the first person to start using a new innovation, or the last!

*

Only it was much better written that that.

It's really buggin me, so if someone could help me out here I'd be grateful!
