The beginning of every artistic journey is either coupled with doubt or experimentation. The reality is that that is how everyone starts to a large extent. While some individuals may exhibit artistic skills from an early age, some of us tend to land on our path by accident. The reality is that everyone can be creative, and it just takes time to work on the craft. While the first painting or drawing may not look amazing, over time things improve. Therefore, like every other skill, creativity can be honed by every individual.
I find that creativity is a skill and to be great at it takes intentional time investment. Due to the expansive nature of the creative field, one is free to explore different methods of expressing their artistic nature. Furthermore, you tend to get better with time as you keep creating a piece over time. Aside from this, you learn different ways to get to your result through incorporating experimentation.
