Many interviewers and entertainment writers have described Twilight Saga actor Kristen Stewart as “cautious” and “shy” - even a “Self-proclaimed introvert.” I am not presuming Kristen Stewart is shy, introverted or highly sensitive, and I don’t know her personally. But just from my gut reaction to seeing her in movies and interviews, she does seem to have all those traits, like many other very talented actors.

Winona Ryder admits there have been times when she has thought, “I’m too sensitive for this world right now; I just don’t belong here. It’s too fast and I don’t understand it.”

Many talented and creative people report feeling incompetent, inadequate and having low self esteem at times. But there are ways to shift those feelings and build self confidence.

Self-centered, vain, conceited, egocentric - these are some of the variations on the idea of being narcissistic. We need a healthy degree of positive self-regard, of course, but when it becomes distorted, it is considered narcissism.

Many talented people, including actors, sometimes have insecurities and impostor feelings, a sense that they are a fraud, not really talented and will be "found out." But feelings like those can be shifted toward self confidence.

Finding meaning in creative work is deeply important for actors and other artists. Conscious choices to make their work - and their life away from work - mean something can fuel an artist's creative expression and power.

Summer Bishil stars in “Towelhead,” about a Lebanese American girl’s coming of age in Texas during the first Iraq war. "To Bishil it was a relief to find a part that not only suited her ethnically but actually resonated with her. Still, she found one particularly violent scene was upsetting. Afterward, she remembers going back to her dressing room and “having a little emotional tantrum and crying. And being very sad. I was really tired too... I didn’t realize the toll it took on me, until now.”
