First of all, congratulations for having the balls to do street game.
Maximize the body language that you learn (see) from all of the interactions. What you learn after some 100 approaches or so will help you progress to the next level of day game.
Yes, majority of people (men and women) are busy during the day so your odds of stopping someone is very slim not unless you want to cross the thin line between pick up and sexual harassment.
The next stage in day game is to identify the venues where women spend 10 minutes or more of idle time and then sarge the women in these venues when they are seated. What you learn from street game will help you a lot in this next, higher level of pick up/ seduction.
Hint: Church services and prayer meetings venues, bus stops, university/college canteens, and so on.
