7. Brené Brown

The Power of Vulnerability (2010) Smug, platitudinous and all but meaningless. An awful lot of self-help waffle here about the importance of letting yourself be vulnerable, because without laying yourself open you won’t experience joy or emotional growth: let yourself “be seen, deeply seen, vulnerably seen”. Of course, Brown is herself a very smooth performer who I suspect would die rather than actually be “vulnerably seen” at a prestige event like this.
