OK. One broad category of behavioral activities I have come to value above others is the creative arts with an emphasis on that first word. Take that broadly, since I have engaged in photography, music, theater, various forms of written products and more. Let’s focus on music.
My parents were musicians, though nor professionally. So I grew up in an environment where music listening and playing was a regular part of my days. I heard them comment on music - including popular music - on their own efforts to play well, and on musical artists they liked and why. Interestingly neither of them was particularly focused on the creative side, themselves. That is neither composed or wrote songs. So where did my interest in writing songs come from?
In addition to dasein, I would like to add in built in temperment, though it gets very hard to say how this plays a role in music creation. I just want to say it is there. My parents commented that unlike them I took an interest in creating in ways they did not, despite the fact that their parents also included musicians. IOW I seem to have had a tendency to make my own art and in my own way, rather than say wanting to faithfully recreate the music composed by others.
This later got intensified by my group of friends, coming in from ages 8-12 and staying into my thirties, with some still friends from t his group. These were people who through humor, physical creativity, and then within traditional categories of art, were always exploring new ways to do these things. It was a very playful group of males adn their was some drive to do things in our own way, together and separately. Any tendencies I had in that direction got increased in their company.
I found some pleasure in being able to play the songs of someone I liked. But not much. I always saw it as an excerise in learning how to create myself. The concept of a cover band or the nailing a guitar solo I thought was great was of very little interest in an of itself. I loved the feeling of making something that did not exist before I made it. Of course I wanted it to be good.
Later I found out that one of my parents had wanted to be a composer, but had thought it would entail too much ruthlessness in relation to his family. Perhaps this was in the air at home. This denied urge. And I picked this up by osmosis.
I went to Montosorri school when quite little. While not particularly more focused on creativity, at least, I don’t remember it being so. It is a very physical pedagogy. The pedagogy itself is quite creative and multimedia and this may have given me more of a sense of possibility regarding doing things in generally. Creativity is founded on being open to possibilities. So perhaps this acted as a cultural quality that at least allowed it to be more likely I would focus on creativity.
Since my parents were talking about creative people - though also on technical artists like other musicians - I may also have thought that there is value in being that kind of person. One of my friend’s fathers was vastly more focused on creative people and was a clearly frustrated creator in a number of arts - he did want to make his living off art. He became a kind of extra father figure, though chicken and egg issues come up in determining if my built in interest drew me to him or he helped create my interest.
I had a short attention span for things I was not directly interested in. I probably would have gotten a diagnosis - ADD, ADHD - if it was nowadays. Creating I find interesting. Rote learning I do not. I often did assignments in school in ways the teachers did not intend and this was for me to make it interesting for myself. This started very early and was noted - both as a postive and negative by teachers. Usually negative. Where did this impatience come from? Well, I went through some serious traumas as a kid. This can make some people want more instant gratification and also to not being willing to suffer their way through details and be disciplined in certain ways, since they are already suffering. Or it could have been genetic - my mother had similar tendencies, though she also went through similar traumas as a child. But then it also could have been that I was normal. That we all find sitting in rows learning things out of context, keeping still, to be a kind of torture. The difference is I allowed my reaction to take more space. Perhaps due to parenting - I was an only child, one parent had hippyish tendencies - perhaps due to genetics. Maybe stubborness was built in to me.
To keep things interesting I was creative. Or tried to be. Once this made things more interesting then all boring situations were essential triggers for me to train creativity - as well as I could, given the general hatred for hte creative in the education system and elsewhere.
Anyway, that’s a bit of an attempt to satisfy the request of the OP. I can say more, but perhaps am not doing it correctly. I did not choose what it generally consider a moral value. Though I think it is one. Or since I do not grant morals some kind of objectivity, anything that leads to behavior is in the same category: values. Perhaps I should be doing something else. Perhaps other people should be. I value creative behavior more than other behavior. Not all behavior, but much of it. I prioritize it.
