You're in great company! Everyone stinks at skateboarding when they first give it a shot. Of course there are those who get the basics down fast. Other skaters require more time to get used to balance, feel, and the particular motions of skating. All skaters learned helpful tricks/tips from their friends that helped to learn quicker. So here we'll cover some helpful tips you can use when you're looking for your first skateboard and start learning to ride.
You might need a little time to know which foot goes in front and which is best in the rear. Whether you are right handed or left handed doesn't really come into play here like it would in other sports. Instead you need to figure out which of your legs is dominant and which isn't. The best way to do this is to think about the way you approach things. When you kick a ball, which foot do you use? When climbing stairs, what leg/foot is the first step up taken with? If you ever trip and start to fall, if you can catch yourself - which foot always goes out first? That will be your dominant leg, and it normally stays to the rear of the board. It has everything to do with your stronger leg, and really nothing to do with direction you're facing. Come to terms with any fears you have. You'll see many beginner skateboarders who are too afraid to try much. They quickly see there's not much to save them from getting hurt while they're skateboarding. It's really important to face this if there's any hope for improvement. If you refuse to deal with this kind of fear, then you'll always be on the outside watching others do the tricks you want to do, too. Really, the only way to effectively deal with this is constant practice. The more you practice, the more you'll become willing to try new things. Learning the best way to fall will help you, too. The more of these things you deal with the less likely they will be to scare you and the better you will be at skateboarding.
Learn tricks one at a time and start slow. It's safer and better to make sure you have the basics down, first. Don't go skating down the stairs or doing big jumps. Do some small lifts and changing directions. You can jump the board, then change direction. Get these basic tricks down, then try something more dangerous. Learn tricks slowly and practice before you try something you really aren't ready for. Anybody can learn how to skateboard. If you can be patient and learn slowly, then you really can do anything you desire on a board. Having patience is really it - see you there!
