The goal is to have 5 potential dates within a week.
That's a good target to focus on, ok?
Now, the only way to achieve that is to practice a lot!
Don't email just to girls you would date, right now, the first goal is not to get a date with the girl you will spend the rest of your life with, it is simply to practice and connect with as many girls as you can.
