If I had to chose a favourite piece of advice it would have to be this one.
"Always trust your gut. It knows what your head has not figured out yet."
In my opinion, based on both personal and professional experience: For a satisfying, successful life it is vital to connect with your 'gut' - your intuition - your spirit!
Better to make big decisions having checked in with ALL of you, not just your brain!
