Yes, this more accurately reflects the current understanding among psychologists.

I'm not so sure about this. You appear to suggest that the behavioral patterns which make up our personality exist because we prefer those traits over others. As I'm sure you're aware, personality is also a product of complex interactions between our genes and the environment (neither of which we have a whole lot of control over). I think many people have personality traits that they don't particularly value. Many introverts, for example, might prefer to be more socially competent and outgoing. Many who are impulsive would prefer to be have greater control. Some who rely heavily on thinking through everything in a highly rational manner might prefer to have better intuitive skills and vice versa. I think most people would try to achieve a greater balance if they could pick and choose personality traits (a little more of this, a little less of that). They might try to tailor their personality to be more congruent with their career to enhance their success and work satisfaction. They might make changes designed to enrich their relationship with a significant other and gain the satisfaction that comes with enhanced intimacy. Too large of a change would, I agree, be too scary for most.
