It is highly important to start developing your ability to use your weak foot from the early stage of learning soccer to be able to make it a habit, a natural and spontaneous ability that will impulse your skills and dribbling to a very high level. When you are able to use both feet with the same ability you will become a more unpredictable, confident, and strong player.
If you are able to dominate the ball with both feet you will become a more versatile player and be able to play in other positions to help your team. To start developing this ability your need to work out all the time with both feet, all juggling, dribbling, and passes of the ball will need to be done with both feet, daily kicks to the goal with your weak foot, and using the right tools like a juggling trainer net will help you to reach a good level of control with the ball. Another way to try to improve your weak foot is to try to do things you would do with your stronger foot like shots from outside the box or long passes.
