However, when it comes to creating art, there is no one ideal. It can be done mostly logically, mostly emotionally, somewhere in between where they are at war, somewhere in between where they're in harmony, or somewhere in between where they're in a love/hate relationship. Finding just the right measure and blend for the kind of art you're making is therefore your task.
Often, great art is associated with emotions. And while it is true that some of the most beautiful art is heavily based on emotions, we cannot deny that some of the most brilliant art is heavily reliant on logic - which may or may not be explicit.
It serves to recognize where your talent lies rather than to lean more one way or the other just because you believe it'll make your art more worthy (given what your peers appreciate or what you heard or read one time). You can still develop in both areas - and that's advisable. However, it would be a waste not to take advantage of what you're innately advantageous at.
Yet, sometimes it is not about talent or what you're most by default. There may be times in your life when you're more capable of using logic than of experiencing emotions and vice-versa. You may call these logical times a dry period. And you may call these emotional times a drowning period. Both may give way to something worth making. And if not, you can take it as a cue for a break.
