Carl Henegan said this quote

Here is how the universe works, whether it is in business or personal relationships. The more you second guess, doubt, and try to cover everything that could go wrong “before” you enter it, the more you will discover the need to do it. However the more you approach life and each new connection with open arms and trust, the more positive and elevating souls will enter your path in which none of the doubt is needed. Even the negative moments are positive lessons.
