“If you think you are too small to make a difference, you have never been in bed with a mosquito”
The earliest known example of this quote comes from a January 1993 article in Time magazine, where it is associated with British businesswoman Anita Roddick:: "Even Body Shop trucks are employed as rolling billboards for pithy slogans. Roddick's current favorite, taken from the side of one of her company's lorries: IF YOU THINK YOU'RE TOO SMALL TO HAVE AN IMPACT, TRY GOING TO BED WITH A MOSQUITO".
IN the 21st century, it was cited as an "African proverb". Earliest attribution to Dalai Lama is from 2004.
