When someone says “Don’t let somebody else…”, “Watch out for this type of person”, etc.

Any practice, group, system, philosophy, or individual that promotes being distrusting of others, or blaming other people or unseen forces for your own condition or circumstances, well-meaning or otherwise, is leading you into A trap that will perpetuate For you the very things that trouble you. It is not a coincidence that the only common denominator to the circumstances and conditions that “keep happening to you“ is you. Seek instead to gain consciousness of your own creations and projections.
