You make photos, you make illustrations, you make videos, you make music. You derive artistic stimulus from all sources: from listening to music, from films, from dance, from exercise, from philosophy — from anything!
To develop to the fullest extent– grow more variegated. Consider a tree. You have a singular trunk, but your roots grow deeper into the soil, and your branches continue to multiply, and grow higher and higher (while growing wider).
Strive to master MANY artistic domains in life!
Furthermore, strive to engage all forms of knowledge. Science, art, humanities– it is all good!
All arts which inspire and stimulate you are good!
And above all; focus on artistic creation, and your own artistic productivity!
