DDA is just one of many conmen known as gurus in the seduction
community, a circle that is hell bent on scoring with women for
flings...they sell very similar "advice "and they hate one
another's guts. 
You have to remember that the women that these guys talk about
are the there's-nothing-no-one-has-tried-on-me, "untouchable" sort.
It's good for breaking the ice with them, but no matter how much
you practice, people do not change, and you can cover
your true self or only so long.
You don't need conmen to tell you the only important things you
can take away - be a man, stand up for yourself and work on your
self-esteem.
People can change, if they realised the need to change and learn
from others what needed to be change.
And yes, they should be themselves and stand up like a Man (Not
Mari Kita pls....CB). But that is ONLY possible after they have
changed from a boy to a Man.
If they try to stand up like a Man when they're still a boy,
then they will be rejected as a boy instead of respected like a
Man.
Having real confidence with their own strengths and weakness is
a plus point for a Man. Cos nobody wants to be with a loser who
isn't comfortable about his own weakness and neither do we want to
be with Mr. Perfect who never admit his mistakes.
Sometimes it's cute when guys makes some mistakes to allow
us to tease them a bit. And sometimes it's a bit hot
when they are comfortable to admit to their mistakes
while still maintaining their level of self-confidence. 
Children can all go play their ma-sah in the playgrounds and
punks can go play kof in arcades.
