You Know You're Good Enough, So Why Don't You Believe It?Highly successful people often know intellectually that they are not failures, but truly believing it is another matter. A psychologist explains why.

Krista Regedanzis a psychologist in Palo Alto who specializes in working with business leaders. She often sees them struggle with distressful thoughts, feelings, and behaviors — thinking they're not good enough, or that they're failures — particularly at the nexus of an accomplishment, like a round offund-raising, or when they're teetering on the verge ofburnout.

"A lot of the intellectually astute people I work with come to me knowing, on paper, that they are not a failure, that they are good enough, normal, OK, or free," she says. "And yet, there is a sense that these positive thoughts are not believable."
