It's a strange feeling. You know what you should be doing, or should be saying but the feeling makes you hesitate and question yourself. Going any further would result in some level of vulnerability that you believe you're not mentally prepared for. In these moments many choose to not act, not speak up, and will remain in their comfort zone. As a result an opportunity is missed. It's in these moments I believe you should "Embrace The Awkward", because on the other side of awkward is a better, more honest reality.
