The trouble with 'good' advice (and here most of the 68 bits I agree with) is that it usually comes too late to be of advantage. When one is young and receives such advice one hasn't the wisdom to recognize its importance. Eventually—after one's gained wisdom through having ignored such advice and reaped the consequences—it comes as an annoying reminder of how one should have acted.
'Tis a great shame wisdom can't be a prerequisite.
