The simple trick to save yourself a lot of headache, emotional pain, obsession and spent mental energy is by having more than one option.

You meet one girl, you have to quickly no matter what at a minimum meet a second girl and start talking with her too.

This minimize the chances of over interpretation of every minute detail of every interaction with any one girl and also blunts any rejection and solidifies your responses from a position of strength.

You become much more carefree automatically. You do not obsess and do not mind minor issues that may arise, because you have leverage.

This in turn ironically makes you even more attractive. Because as you are not so deliberate in your actions but rather more relaxed and natural she is more likely to be drawn in.
