Autosuggestion or a process by which an individual trains the subconscious mind to believe something, or systematically organizes the person's own mental associations, usually for a given purpose.

This is accomplished through self-suggestion methods or repetitive, constant self-affirmations, and may be seen by some as a form of "self-induced brainwashing".

Whatever one thinks, whether with a negative attitude or a positive belief, it will usually determine what the results will be!
