There are plenty of gems hidden in the dross of the Self Help explosion, and the generalized sanctimony the OP link seems to wave over the entire subject is itself (I would offer) suspect on the same grounds it claims. Claiming to have the expertise to define the internal landscape of the individual or the ultimate analysis of the individual's place in the world is pretty presumptuous. I have always considered it a useful guideline to invite people to find out for themselves which truisms and mechanisms they find match their own experience and perceptions. Absent that, all the advice in the world is just vapor.
