Don't Tell Your Business....#Duh
I heard this concept mentioned in a few circles casually and decided to do some research.  This article is pretty cut and dry.  There are many studies conducted that have reached the same conclusion; the more you speak aloud your goals, the less likely you are to execute them.  My personal spin includes a trust factor.  You just cannot trust that everyone you're sharing your business with has your best interest at heart.  Even your friends will spill the beans mistakenly.  Keep your lips tight and your pockets will thank you.
