This will give you a basic layout of how to strike a soccer ball so that it has power and accuracy.
Step 1: Before striking the ball.
Obviously, make sure you have proper shoes on (preferably soccer cleats) and be sure you're kicking the ball at something like a wall or a goal so you dont have to run and get it everytime.
Place your ball where you want to strike it from. Stand behind the ball so that you are facing the target that you are aiming at. Now, take about 3 steps straight backwards. If you are right foot dominated, take one step to the left. If you are left foot dominated, take a step to the right.
