Practice
Practice is the only way to get better at anything. This is true for basketball, algebra, needlecraft, scuba diving, playing the violin, and boxing. Playing go is no different. As a beginner one can be tempted, being frustrated much of the time, to look for "magical doors" that would make you a better player without taking the long way around. But they don't exist.
Fortunately, there is a kind cycle that the gods have bestowed on most things, but works especially well for go (at least at the beginner levels): The more you practice, the more skill you have. The more skill you have, the more fun you have. The more fun you have, the more you want to practice.
