I have no secret spots. In this part of Michigan every place I have ever fished shows plenty of signs of previous anglers in terms of litter and beaten down bank-side paths. I try to limit help to one or two ideas not because I'm protecting whatever knowledge I have but because that seems to be enough to assimilate while on the stream. I have long since lost count of how many leaders I have reworked while explaining about the use of tippet material. That and a quick explanation of mending will let most beginners who were getting skunked start catching fish. I think the most I have done with strangers was trading a casting lesson in the parking lot for beer from a guy who asked for help assembling the kit he had just bought.
