The best way and the only way that you will learn any new skill is one successful and unsuccessful step at a time.
This is a very important fact, learning a new skill almost always starts with a lot of unsuccessful steps before you start improving.
For example, if you are learning to play a guitar at first your fingers will be very clumsy and not touch the right cords.
Every person who has become accomplished or an expert at anything has put in a lot of hours practicing and has worked through a lot of setbacks!
Therefore, if you keep practicing and working through your unsuccessful steps you will get better and better at whatever new skill your trying to learn.
