Tarot cards are a tool you can use to help you on your life's journey, helping you understand who you are, how you got to where you currently are in life, and most importantly how to navigate your future to create the life you want, and deserve
The cards are a divination "tool", an avenue for you to use in your own self-discovery. The cards tell a story, your story, and can help you see and plan the future you desire.
Anyone can learn to read Tarot cards, you do not have to be "psychic"; that said, everyone has psychic abilities yet few choose to embrace those abilities. Once you learn to embrace the fact that you are more than just a "flesh and bone" being you open yourself up to discovering, to noticing the energies around you. You can then hone in to your own psychic awareness to connect more deeply with the messages coming through the cards.
Practicing reading the cards for yourself will help you gain confidence in reading for others, and that is something that is truly rewarding
