Are your mindsets for cold approaching different in the day from at night?

I'm getting my night game down and having much more success, but I'm still struggling at day game. At night I use the mindset of just having fun. I'm vibing to the music, chit-chatting with random people, and then when I see a girl I want to talk to it's much easier to cold approach.

But in the daytime, I can't seem to get this mindset to work. I was at the mall earlier and I couldn't get out of my head. And subsequently I paralyzed myself. The most I could do was talk to the cashier. But as far as cold approaches. Nothing.

What are your guy's day/night game mindsets you have when going out? Any pointers? Thanks.
