Musashi, the most famous Japanese sword fighter, won over 60 1-on-1 duels to the death. He was a true master of his craft but he understood one thing:
In order to balance your art, you must learn many unrelated things such as calligraphy, cooking, philosophy or dancing. You cannot just learn one thing and expect to master it.
Creativity has invisible sources. It makes connections through learning itself.
Be a beginner. Learn as if your life depends on it.
Learn a new skill for the sake of learning something new.
