It took me like one year to build up my confidence to cold approach and it only happened because my friend literally pushed me

Since then I’ve done around 16 cold approaches but the nerves always come back in and sometimes I even chicken out badly. I just feel like after 16 cold approaches I shouldn’t chicken out especially because I’ve only had one success and I’ve had some bad rejections like a girl rolling her eyes and walking off so I just think after experiencing the worst the approach anxiety would go away but it’s still there. I literally chicken out just 10 mins ago on one of the hottest girls ive seen in the super market
