According to Merriam-Webster Dictionary, doubt is an uncertainty of belief or opinion that often interferes with decision-making.
DOUBT. It will affect each one of us in some type of way throughout our lifetime. It may come as a constant, poisonous imprisonment that trickles slowly through your mind just when you’re at your lowest. It perfects its introduction in the mist of your journey when you’re pursuing your dreams, perfecting your craft and working diligently to change the course of your life.
