The approach you suggest works fine in the short term: most of your customers will fail, but only after paying you, and there's a line of suckers behind them.

However, in the long term, if you help a customer thrive by helping them understand what they really need, you might make a bit less off that customer right away, but you'll have a customer for life, and many more where that came from via word of mouth.

I don't think they are suckers, I just have no idea which will succeed and which will fail.

I always try to leverage my expertise to help them but at the end of the day the customer is always right.
