Always have in mind that you can study as much as you will, and you can be a real expert, but if the questioner don't believe in it, the reading itself have no real value.
I will say...give the reading....to the best of your ability ....then let him decide if he want to believe or not.....but don't let his action wear you down because you then know you have done your best, and his actions might destroy the outcome.
Tarot is in my opinion a good way to open for new and better paths to the future, not as much for yes/no or do I win in lotto next week
