What is a good amount of approaches someone should aim for daily in order to actually feel like we become better and better each day ?

I want to approach women, the city I'm in has a lot of pretty ones. But since I never done it before, and pretty much 99.99% of the time a woman is with her friend / friend group, makes me more nervous and overthink a lot, so I get stuck, how to overcome this ? I know there isn't any magic solutions, just need some advice 😅.

The one I closed in the mall today. She agreed for a coffee next week. I was thinking of sending this as my first message after I got her number based on the compliment I gave her “Hey the most well dressed person I saw today, it was lovely to talk to you today. Hope your piercing treatment went well.” Any tips or suggestions?

I would appreciate if you can help. I have attached two audios of myself. Met Lina on my first day out, and the second recording is from second day. I am generally confident because I have sales background. but I was energetic on first say and got 2 numbers, although my approach was shitty. 2nd day my energy was just not there. even after approaching 5 girls I was not feeling it. I was not smiling much (as I was feeling low) and not striking ant fun convos, making the interaction weird
