Presentations or essays like this frustrate me, because I can understand what they are saying on one level, but then am usually left clueless as to what to do about it. There always seem to be assumptions, too, or at least undefined terminology. Brown starts with the idea of connection, which she never defines, and the assumption that we all need/want it, without justifying or qualifying this (e.g. do we all need the same amount or kind of connection?) She explains her idea of shame, worthiness, and authenticity a bit better.
The central idea of vulnerability, though, is never really defined. The word "vulnerable" is based on the latin word for wound, suggesting it is the ability to be wounded, or hurt. The examples Brown uses to illustrate it seem to focus on risk. In most areas of life, however, people are encouraged to avoid hurt and to carefully control risk. We wear our seatbelts and install smoke alarms; we buy insurance and invest for our retirement; we make up wills; we buy generators or stockpile supplies. Brown doesn't seem to think we need to exercise similar caution when it comes to the area she is discussing, however (emotions? relationships? not sure even what to call it). Maybe this is why advice like hers tends to come across as unworkable.
