When you hear the phrase "follow your dreams", does it make you think that you have to quit your job and drop everything? I think it's a very common after thought. Barbara Sher has said that if you quit your job to become a painter, you'd go nuts. You could never just drop everything and paint all day, or sing all day, or be with animals all day.
Start slowly with whatever it is you are doing. One of the worst dream killers is taking something you love and expecting it to make you a living immediately. Aside from winning the lottery, the "overnight success" is actually the result of many years of hard work. Even one hit wonders have to practice in their garage before someone hears their song.
Eric Maisel, who trains us creativity coaches, has said that artists and musicians need plenty of practice. While the dream to become a dancer is glowing within you, you will get no where unless you dance and dance and dance. Have you really been practicing and practicing all these years? If so, good for you! If not, then get going. When you start slowly with practice, you will get experience and exposure in your field of interest. Also, you will know if dancing, for example, is truly for you. You may only like to watch dancers and may learn that promoting ballet may be your true calling.
For now keep paying the bills with your current job. If, however, your job is toxic, look first to getting a new job that will keep food on the table. You need to take care of yourself financially before you can venture down a new path. And when you venture, do it slowly. Pay the bills while building the dream.
