The first thing that you need to do, is to go on and realize that Ronaldinho is the greatest on the pitch trickster the sport has ever seen. Based on that, you need to watch all of his videos and highlights, so you get a mental idea of just what you need to do and just how you need to do it.
You might not be able to copy what he does, since he has proven to possess exceptional talent, but you could try to follow in his footsteps.
Another thing you need to do, is to practice juggling the ball. Juggling the ball will help create a mental coordination between your foot and your mind, which will allow you to start feeling the ball better with your foot.
This is going to be essential in later parts of life, when you only get seconds to beat defenders.
Practice ground moves
The next thing you want to do, is to keep the ball in your feet when you are dribbling on the ground. This will help you become one of the best at being able to feel the ball with your feet, and will give you a definite edge over everyone else.
Practice against hard hitting tacklers
The next thing to do, is to take all your newly learned skills and look to play against hard hitting tacklers. This will really test your ability and show just how good your really are. You might end up getting injured the first few times, but there is no gain without pain.
