Like someone already said, it happens to everyone. I was thinking the same way as you man, i saw some guys with no game getting numbers and dates with ease.
It takes time to get good at game, so take it easy and enjoy the process. First you get good at approaching, then your mid game sucks. But after couple of approaches, your mid game improves. Then you suck at closing, but then you push it to the limit and finally close (i remember my first n-close...sweet

...) After that you suck at texting, getting day 2s and so on. But guess what? You will get better. Its a law. Thats how it goes. You have to fall in order to learn how to walk.
About setting up day 2s: girls flaked on me so many times. I was really pissed. But then you think a bit about it. What i learned from my experience is that getting n-closes is not your first option when you close the girl. INSTANT DATE is the best option, but as we know, sometimes is not possible. So then you get her number and say to her that you would love to go there and there tomorrow, not next week, but soon as possible. Dont text to much. Text her just to set up a date and little flirting and thats it. Dont overdo it.
Establishing comfort and kino is something you have to do when you go for the number. She must get to know you a bit, so you wont be just "some guy" she meet. I know, you cant get to know each other that good when you pick her up in couple of minutes, but you have to establish some level of comfort.
Hope this helped. Keep approaching
