When we allow doubt to infect our consciousnesses, we do ourselves a great disfavour. We not only allow negativity to overwhelm us, but also to give in to false reasoning which can stymie our growth, whether on the physical or spiritual level. It is one of the quickest ways to halt our progressive incline and begin to decline. We must be on an upward spiral; not a downward one. So, give those doubts away and progress another day and our losses can stay away!
