The best way to begin working with elements, is to research them all and then work with all of them. After you begin working with them you will more than likely find one that is easier to work with than any of the other, one you feel more drawn to. That would be your element. You can also have more than one element so don't just close yourself off because you think you found the "one."
It is also best to keep working with all elements even if you have found the element your closer to. Elements work best when used altogether.
