Great topic.
I disagree with magnum45 and think that being a PUA is not about pussy...getting pussy is a result...but, on the road to getting pussy, as we examine ourselves, we do find it becomes about certain core beliefs we have about ourselves, the world, and women (and even God, if you're a theist).
So allow me to contribute a few thoughts that guide me (most of these will have to do with me, and my world, less so than on girls).
1) My voice has depth, power, and resonance. it is akin to voice of God. I use it boldly.
2) When I smile, I'm a ten
3) Deep down, I'm a bad-ass. So I won't pretend to be anything else. People love my bad-ass side.
4) In any room I'm in, I'm probably the most confident guy.
5) Confidence: a firm belief in one's own powers.
6) Insist on being the politician/businessman/lawyer/writer/minister that you went into the field to become. Lesser beings with smaller destinies will try to shape you into their image of that role, but you must not allow them. Furthermore, refuse to be judged against your predecessor.
7) You choose your level of joy. Also, don't be responsible for the joylessness of others. Today, I choose to be joyful.

The Universe will always give you that which you are after, but only if you are ready for it.
9) I love my life.
10) In structure, problems and games are almost identical. Except for the level of abstraction, and of course, the perceived consequences.
11) In structure, problems and games are almost identical. Except for the level of abstraction, and of course, the perceived consequences.
12) I am the prize. They are all auditioning for my friendship.
13) Practically everything in the universe progresses according to predictable patterns, regardless to whether these patterns are known. Wise men discover these patterns and exploit them.
14) Anything can be learned.
15) I eventually succeed at anything I put my mind to.
16) Never ever, never ever, never ever settle. It way be the gravest of all sins.
17) if you don't get somewhat excited about yourself, who will get excited about you?
18) By and large, you're only as successful as your systems.
19) Destiny pulls us towards while tradition pulls us back
20) By and large, we're dealing with a Personal God, who cannot be manipulated because He makes His own rules, and a Mechanical Universe, which can be manipulated because it obeys rules faithfully. Therefore, love the God, cultivate relationship with Him, and pimp the universe.
