Basically, there is no way to separate people who are just playing from people who are in earnest. If someone is just sharing daydreams, it’s often a little boring.
Also, there exists a type of dilettante who is ever so slightly . . . smug . . .about his pseudo-ambitions. There is this tone of “I’m going to be an artist, I’m not meant to work in a cubicle like you shmucks. I’m an artist. I FEEL more. I am special.” This is frustrating because we all have creative inclinations, we all have rich and complicated emotional lives. We all have found some sort of compromise between that and the need to support ourselves–and that compromise does not always mean “selling out”.
I used to get this a lot at graduate student mixers I went to with my husband. I got a lot of pity and scorn when I mentioned I taught high school–the ultimate in selling out. But all these people were planning on going to NY, planning on going to LA, planning, planning, planning but in practical terms they were piling up debt and patting each other on the back. I didn’t mind that, but I minded that they pretty openly (at times) looked down at my choice, when I’d argue teaching is as creative and emotional and artistic a vocation as any they had ambitions towards, and more so than anything they were currently engaged in.
