Will Yourself to Meet Girls But Have Fun
When you're trying to get better at meeting girls, part of you needs to have a "mission mentality," where you are focused on taking particular actions that lead you to making decisions that lead you to approaching, engaging, connecting and closing with girls. It's necessary to have that mentality or you'll never do it.
If you do not orient your mindset and physiology to it being about fun and providing fun to the girl and others, then you will become too serious and rigid about it - ultimately sabotaging yourself in the inevitable moments that require calmness, good emotions and flexibility - such as dealing with randomness in the environment, working with her emotions, closing for sex, allowing yourself to get aroused, and having sex.
So be on yourself to take action - but have fun!
