First of all, you don’t need to be psychic to read tarot. You can read purely through interpretation: symbols and their meanings, plus how they interact in a spread. Some of the best readers do it that way and it’s exactly why anyone can read the Tarot. Democratised insight and intuition! Yay!
But if you are seeing signs or maybe you just want to develop a practice outside of the cards, then there are things you can do, but they’ll all take a lot of work. There’s nobody (and I do mean nobody in my experience) who just wakes up one day able to do all the crazy things you see on TV.
It all takes work and effort. Sometimes years of work.
If you already practice with the Tarot, I would keep doing that, and your psychic gifts will follow. Chance practice, not external factors. Just let them show up since you’ve already put work into reading the cards you don’t want to start from zero again. You’ll find it a lot easier to use other tools later if you choose to but don’t keep jumping from idea to idea.
Don’t chase the psychic side. Chase practice.
