Assumptions are the natural thought process (both conscious and unconscious) of the human mind in which we are forced into perceive into reality with our limited, imaginary beliefs without proof and without considering the end result. It can be both good and bad. We can really get messed up in our problem solving and critical thinking if we continue to proceed in our actions based on invalid assumptions. We must always validate and test our assumptions to be sure that our assumptions are based in reality. We must always avoid jumping to assumptions especially if they are negative or illogical. Critical Thinking is very dependent on the open assessing, validating, and clarifying of assumptions. You're your dominant thoughts. Essentially "if you really want something and assume/believe it's possible, you'll probably get it" Your dominant thoughts will find a way to manifest your assumption, not plain assumption, but the assessed, validated and clarified one.
