I would also like to add that using ones common sense can help a great deal! I know I have gotten into situations when i was brand new into the lifestyle and I would like to say I did some stupid stuff so I know how it is lol. I know not everyone has common sense but there has to be a gut feeling some where that tells that person "this just doesn't seem right". Plus asking around helps when making decisions, also trying to find a mentor can help also.
