Probably, but we always seem to do that!
Here's a counterpoint thought to your point about the artists who succeed due to serious personal issues - just think it over for a minute before dismissing it out of hand:
Let's say for the purposes of discussion, we have a couple of options:
Option One: We choose to spend our life doing something we love that we think has a very good chance of fulfilling our human potential.
Option Two: We choose to do something that we don't love; we choose this despite knowing it will make us unhappy and we feel it doesn't fulfill our potential as human beings.
All things being equal (i.e. money not being an object in the discussion), most people will choose Option One. In fact, this is Alan Watts' recommendation.
Anyone choosing Option 2 when money's not in the deal has more problems than someone choosing Option 1, in my estimation, since people like to enjoy their lives.
BUT- then we insert the Big Monkey Wrench into the situation: Money. $$$.
Option One carries more risk of not being successful! So we do things that may not be as fulfilling, and that's considered normal.
Question is, are people who pick Option 2 for money actually happier? We can actually look at suicide studies in a certain population and get some inkling as to whether that's the best idea.
Let's look at doctors, who most folks in society feel are very well set by most standards, and have generally high incomes. One meaningful thing is to think about suicide rates among such a population, and what we find is unexpected: the suicide rate among doctors is startlingly higher than among the general population:
PERCENTAGE OF DEATHS DUE TO SUICIDE (study I found was white male population, I have no other figures, sorry!)
U.S. white male general population 25 and older (1970): 1.5 percent
U.S. white male dentists (1968-72): 2.0 percent (85 of 4,190) - higher than general population
U.S. white male medical doctors (1967-72): 3.0 percent (544 of 17,979) - double the general population (!!)
U.S. white male population 25 and older (1990): 2.0 percent
U.S. white male medical doctors (1984-95): 2.7 percent (379 of 13,790) still significantly higher than the population (!!)
U.S. white female medical doctors 3.6 percent of white female doctors' deaths were suicides--higher than the rate for male doctors and many times the average for U.S. women (0.5 percent for 1990; source: Frank et al., cited above; Vital Statistics of the United States--1990) (Geez!!)
In a study of 18,730 physician deaths from 1967 to 1972 (men and women), psychiatrists accounted for 7 percent of the total but 12 percent of the 593 suicides. Well, that's no surprise.
So, here are all these successful people having some very serious problems leading to self-destruction! Based on these figures, I might say that artists aren't the only ones with self-destructive tendencies!
Here's the crazy thing: despite the difficulties of life as an artists, the suicide rates are, according to US National Library of Medicine National Institutes of Health, only 125% of those of the general population: 2.5 percent taking into account an adjustment for sociodemographic variables. That is lower than male medical doctors, and much lower than female medical doctors. You'd think this population would be at much greater risk of suicide, since everyone "knows" that artists are a crazy bunch, and since suicides tend to rise in financial crises!!
The point is...it's clear to me that no career is a gold-clad guarantee of happiness. If someone can say, "OK, I'm going to do something that's difficult to make a living at. If it works out, great, if not, I'm willing to take the chance that I may have to do something else for my daily bread," I'm good with that. I think it's ok. I don't think it's crazy.
"My kid's going to med school," is something we think is brag-worthy. "My kids going to art school," has people going, "how will she make a living?" It's odd they don't factor the higher apparent unhappiness rate into it.
There is nothing wrong with a day job if one doesn't succeed, and in fact, many successful artists started out with needing one.
