It seems simple yet it's a battle of guts. Starting a conversation is something, but keeping the flow is an entirely different process. Saying what you want is not necessarily what you need to say unless you want to take a gamble. If you really want to flush out everything you want to say from your heart then try taking the gamble. You'll never know unless you try.
Life is a gamble. Sometimes you lose, sometimes you win.
Try being humble next time.
