Do you think i have potential to become an actress?

hey! i want to become an actress, but i don't know if i can. i know that acting is a very hard job, because you have to practice and practice to be an amazing actress. i can cry real tears but it took me like 10 seconds to be sad and emotional. I can pretend to be sad, happy, angry, and all, but i don't think im good enough. i don't know if im good enough. i really want to be on stage for the rest of my life, but im afraid that the job isn't right for me. please tell me ur opinions, thanks!
