If an idea or fact is sticky, it sticks in your brain without having to memorize it. Malcolm Gladwell talks about stickiness in his book The Tipping Point.
I discovered this way before I read Gladwell's book, (I was reading a book on logic... or was it memory? It said to remember the capital of Venezuela, think of a whale eating crackers) but the idea became more sticky to me after i read about it in The Tipping Point..
Do you know any sticky spelling or punctuation or grammar rules? If so, please share them with me so I can learn with less effort.
Examples:
Gray and Grey: A for America; E For England. Gray, the color is with an A in America, and an E in England.
RAVEN: Remember Affect Verb, Effect Noun (maybe not 100% true, but it helped me)
FANBOYS: For And Nor But OR Yet So
Desert or dessert: You want two desserts, but you don't want to walk across a desert twice.
Thank you for your time.
