Re: Confidence - fake it 'til you make it.
I started with getting phone numbers from women. Detach your self-presentation from your inner self and look on this as an acting exercise. Mentally model what you'd look like if you got phone numbers from attractive women all the time. Look at scenes in movies with characters you like. Practice what you come up with on attractive women. Change your presentation a bit and observe the results.
Done correctly, this process results in a lot of phone numbers. By itself, it won't get you laid a whole lot. However, it can give you a framework for practicing a confident presentation in a context where you are faking it. Also, this happens in front of somebody who already knows they have something you want.
