1. "Gypsy" fortune teller acts. First of all, "Gypsy" is actually a really insensitive word. A lot of people don't know this, so don't feel horrible if you used it up to now or anything. But it's a big-time slur in Europe, and it isn't even accurate, considering it was used to refer to the Romani people because they "looked Egyptian" and no one could be bothered to ask them for the facts. Kind of like "Indians" referring to Native peoples in North America.
The actual semantics aside, if you're reading Tarot more for the entertainment than the counseling angle - and that is totally fine, seriously, as long as you make it clear that's what it is - then you can probably find a sparkly costume to do it in without an accent and the words "cross my palm with silver." Come on, guys. There are like six stereotypes that plays on, and not enough people know what they really refer to.
2. "Bad" cards. People who are reading for themselves tend to do this. A reversal is "bad". The high Swords cards or the Tower are "scary". The Star in the "what to watch out for" position means "you are heretofore advised to throw yourself into a pit of despair and never be optimistic again."
You can read everything super-literally if you want, and I get it if you want the cards to just serve up a slice of truth: "No, the job probably isn't on the way. And also you should probably look out for the bolt of lightning that's going to shake your world up. Just warning you." But I feel like I'm watching a mime box himself in. The problem isn't how you're reading, when you do it this way, it's how you're responding to what it says. I honestly can't, in my heart of hearts, believe your inner guidance and a hand from the Universe is simply saying "Your life will suck right now."
Why is there going to be a bolt from the blue, or a feeling of total despair? You're never helpless in your life, and rarely does anything just happen to you, so determine what's going to show up in your world and decide how you want to feel about that. Adjust circumstances accordingly. Maybe you're not supposed to get the job because there's a better one on the way. Or the sudden, painful revelation will lead to you reinventing your world in a way you'd never have been able to before. Tarot is never just about things happening to you. It's about looking at the road you're on, where it's leading, and if you want to change direction.
3. "They're doing it wrong!" Yes, before you ask, I see the irony here. But seriously, I can't stress this enough. Yes, there are close-minded ways of catering your reading to exactly what you want to hear, or responding to your reading from a place of fear. And that's not good for your learning, or what you get out of reading Tarot. But I'm talking about the methods you pick up and the teachers you choose. There is no end-all-and-be-all as far as that's concerned. The only way you could possibly be "doing it wrong" is if you learn one way, stop there, and refuse to learn anything else. The more information you gather, the more you can decide for yourself what's worth doing and how.
But, here's the real reason for this one: even if you work for years and decide the best way to learn or teach or read the cards or whatever else, please don't be a jerk about it. I have seen a few Tarot experts and instructors call each other out, often by name. I've seen them get judge-y for having a different opinion, teachinga certain way, charging a certain amount of money. I can't think of anything that turned me off faster than watching a seminar from an instructor, and listening to them smugly outline how their teaching was superior to someone else's book.
Everyone learns differently. Everyone responds to the cards differently. Don't limit yourself by stereotypes, by fear, or by inaction. But most of all, don't ever limit someone else by telling them there's only one way to tap into the cards. Tarot is far too elaborate, magical, and full of potential for that.
