I have come to the obvious conclusion that I am a human and my own thoughts are almost always my worst enemy. I get into some level of a rut where I am only thinking negatively about myself when I have the potential to approach nearly any girl.

How do I avoid this mindset?

For instance, I brought home a solid 8 about two weekends ago. Last weekend I go out, notice a really cute girl do an obvious up-down on me, and then I do absolutely nothing. I was too preoccupied with thinking I was inadequate for such a blonde sex goddess.

Anyone have any tips/tricks?
