Your Jupiter sign reveals where you find luck and how you grow. When you feel a sense of optimism that can’t be explained, that’s Jupiter. It doesn’t guarantee a smooth ride.

Jupiter takes about twelve months to move through each sign. Wait. That isn’t right. Jupiter takes about twelve years to complete its full cycle through the zodiac.

The liver is forgiving but not infinitely so.

The planet also rules your sense of humor. Jupiter humor is big and expansive. It tells stories that get better with each retelling.
