>What can you tell me about the nature of creativity?
Ever heard about jungian cognitive functions? Creativity in terms of artistic expression is a product of introverted feeling (Fi) coupled with extroverted sensing (Se) for physical performance related art (painting, music, dance etc) and introverted sensing (Si) for writing and maybe some other things like directing (for comedic/sf type of writing it's Ti+Si e.g. Terry Pratchett, an INTP). Extroverted feeling (Fe) can work too I guess as long as it's high enough in the cognitive function stack but if we're talking that real artsy, ephemeral stuff then Fi is the king.
So if you want to become more creative find out your cognitive functions of your ego (MBTI tests are extremely faulty but they give some reference point from which you can start to figure out which type suits you best - read descriptions of different personalities and if you can't still decide which is more you then delve into the functions and differences between them which will eliminate one type or the other) and then look up what are your other 3 other personalities you can have potential access to (look up '4 sides of mind') and try to work out what forms of creativity you're geared towards and how to get there.
For example: you have Fi inferior? Does that mean you're shit out of luck? Initially you'll suck but with practice inferior function can become a hero leading to an aspirational personality. I haven't seen one agreed upon system of naming but aspirational form has the weakest function on top of the stack so it's ego upside down (should be a no brainer but don't date those who have it in the ego), anima/mirror/shadow/unconscious(or subconscious? I keep fumbling over which is which) is the polar reversal of ego (might seem tempting but the way they lead their lives is incompatible with yours so don't date those either) which means introverted functions become extroverted functions but don't change their position in the stack, and super ego the most difficult to access peacefully, is anima upside down (might seem like what you really want in a partner but they won't understand you at all - your other half which is is 50% your ego and 50% super ego - just switch the T and F letters of your MBTI type, people say ideal matches don't exist but they're retarded; individuals aren't ideal so even the perfect design might not work but that shouldn't stop you from attempting to build from the perfect design if you're going to attempt anything). To access super ego in it's positive form you need to either go through a most traumatic experience for your ego (getting hit right where it emotionally hurts but understanding that spreading more misery isn't the right thing) or master/integrate your anima and aspirational personalities, which is where your suppressed/shameful needs, feelings, wishes, thoughts and so on lie buried within. I didn't do that so I don't know how that works, I went in straight through the trauma but that can easily backfire if you don't have strong enough integrity. Anyway regardless of creativity gain unlocking all of your personalities is a worthwhile goal because it's the definition of emotional maturity.
