You should think about making music as a hobby. What instrument would you enjoy? The next step is to take lessons from someone, or learn on your own with books and videos. Take your time in learning, and you will perfect your ability before you know it!
Be sure to charge a fair price when you make the decision to offer the products of your hobby for sale. Be sure charge an amount that will not only support your hobby but also turn a profit. Add up all costs, including labor and time, then add a profit margin. This is the only way you will be successful.
