Using the 5/25 Rule to Learn to Say “No”
James Altucher

I get the point about saying “no” when it is the right thing to do, but I have a very fulfilled life in large part BECAUSE of the things I have said “yes” to. I have had several successful businesses, I have bought and sold three houses that I made money on, I have a lovely, talented wife (my best YES) and I enjoy life because of the many yeses I have given.

I certainly understand the benefit of saying NO, especially when a yes is what is expected but NOT what you want to say. But don’t stop saying yes just because of past mistakes.
