When you have a visceral response to something you must trust it. Do not pass go, do not collect one hundred dollars! It is your strongest internal barometer that something is not right!
It is easy to try to explain it away, rationalize it or look for more information. That is when you need to stop and listen to what your instincts are telling you. When exactly was the last time your first impression was wrong?
I’ve had a lot of lessons about this in my life and I need to remember to never forget that my intuition will never lead me astray!
