Start Still on Something Soft
Before you take it to the streets, take a couple minutes to practice and get a strong sense of balance by standing on your board on a soft patch of grass, or even your living room carpet. The first time you jump onto a board you can feel pretty shaky, so if you tumble right away, it's nice to land on a gentle surface that won't scrape you up something nasty. Practice basic standing to see whether you feel more comfortable with your left foot forward (also called riding "regular style") or your right foot forward (sometimes called "goofy style"), then try bending and straightening to get the feel of it all. Once you feel really grounded in your stance, head out to some flat pavement to get moving.
