The left hemisphere of your brain controls the right side of your body. The right hemisphere controls the left side of your body.
Another way of looking at the left side is it concerns speech and vocalizing abilities, whereas the right side is non-verbal, visual, or solving problems in non-verbal ways. For example, you don't have to think about how to get home from here, you just get in the car and drive without thinking. Your body remembers the way automatically. It is much more complicated than the simple first answer, but it has to be both sides of the brain that are used, especially in planning for changes in your life and being successfulin goal making or problemsolving.
