It depends how you became a psychic medium; if you had a mentor, they will probably want to keep an eye over you for a while, just till you feel comfortable on your own. Even if you've come to this realization on your own, it can be helpful to get advice and guidance from an experiences psychic. In some cases, your clients might only trust you if you are known to have been mentored or guided by an experienced and known psychic.
From time to time, it may be helpful to seek out the counsel of someone objective for guidance or connection with spirit, and/or to gain a clearer read on your life. If a psychic, medium or any other intuitive healer speaks to you, I encourage you to set your intentions and then simply let go and go with the flow. Spirit will guide you as to who and what is in your highest and best good in that moment. Also, please remember that no one knows you better than yourself, and no one has a closer connection with your deceased loved ones and spiritual guides than you do. By learning to go within, listen to and trust your own inner voice, you gain access to everything you'll ever need to know. And what could be better than that?
Another important distinction is that while psychic readings often focus on predicting future events, mediums primarily tune into past and present issues. It's my opinion that predicting the future, while sometimes helpful, runs the risk of disempowering people. Always remember that you do have a say in how your future unfolds. Despite what any psychic or medium may "see" in your future, it is important to remember you were given the gift of free will when you came into this world, and at any moment in time you can absolutely redirect your course and create the life you want by changing your thoughts and actions. Psychic information is often just insight into what potentially could happen based on the road you are currently traveling—and it should be used only as a guideline to help you make the best choices for yourself. https://drive.google.com/file/d/1f1aV9WNjmLz9QOGcWxBFqipybv-Bwp4D/view?usp=sharing
