As someone who makes stuff of pretty low quality it is obviously an interesting question, I think I have some of the answers, maybe it could help someone, or if someone tells me I'm wrong maybe I'll learn something.
I could wait until I become actually really good at something to prove my point, but that might take a while...
- Find a good teacher, with the emphasis on the word good, many of the best artists were taught by other great artists or shared a teacher with other very good artists, this one is difficult though.
- Find the right community, it's quite common for people famous for the same or similar things to come from the same area or go to the same school or be part of the same scene, it's not just that it's not what you know it's who you know, sometimes none of those people have particularly good connections at all. It's a lot easier to integrate into a culture and build on it than it is to start on your own; most people need other people as a source of feedback, encouragement competition, collaboration, inspiration and so on.
- Have role models and take them seriously for inspiration, reference and motivation and so on...
- Be honest art always carries some sort of message even if it's vague or contradictory, if it's not expressing what you really feel or like I think people will notice and it will put them off, pretensions aren't appealing and neither is complete unoriginality.
- Be reasonably objective you have to be capable of recognising what you are doing right and what you are doing wrong.
- Be invested in whatever you are doing for it's own sake , if you are just doing whatever you doing for money and attention it's likely that whatever you do won't be good enough to get any money or attention because it's very hard to do something well if you don't care about it, having other motivations as well is fine, probably the more motivation the better.
- Have an overall positive and optimistic attitude, being too positive might not be sustainable or honest, but our primitive brains respond much better to positive feedback than negative feedback, being excessively negative will just cause you to lose motivation or cut your ear off or something.
- Take inspiration and instruction from other things you know if there is something that you know and like it could be a good source of inspiration instead of copying subject matter that might have already been done to death, a lot of skills from one activity have parallels in other fields, for example they way you approach composing a tune, a sentence or a picture have more in common than you might think.
- Give advice advice might help someone or not help them, it might even harm them, but teaching others is a very good way for you to learn, even if doesn't help the person you are teaching (maybe that applies here...).
- Find a philosophy it doesn't have to be necessarily deep or well articulated, if you want to do something you need to justify it to yourself somehow.
