Before the questions, I should talk about myself a bit. Im 17, on my last year of High School. These last 5 years (HS is 5 years where I live) has been rough. I was very insecure, lost the majority of my old friends and spent all my time alone. I've been better this year but it's still not where I want to be. I don't have any real best friend and never had a real girlfriend. Best friend kinda happens naturally so im here for girls tips.

1) Is it bad if I fantasize/daydream about my success a lot? For example, before going to sleep or while doing my jogging I create escenarios in my mind where I'm being a total alpha and the chck is super into me and shits. Nine times outta Ten it's about the same girl wich I suppose I have a Crush on her even though we barely talked to eachother. I said like a total of 4 sentence to her no joke. Usually those fantasies happens when im alone and have no real opportunity to make a move. I just wonder if those could create false expectation for when im going to make my move (hopefully it happens, back then I used to give up)

2) Is it okay if I start talking to her on Facebook first? I know people on this sub are pretty favorable towards cold approaches but I feel like the setup is just not there. I see her everyday in class but those are pretty serious class where you can't really socialize unless the person is sitting next to you. She's also always sitting far away from me. I waited so long to make a move since I was hoping one of my teacher would pair us up together as lab partners because they would always switch it up for some reason.

Anyway, now there is only 2 months left of school and I don't want to regret my last year like I regret all my past year. I wanna try for once. It might go horribly wrong but at least I would've given it a shot.

Sorry if there is any grammar/spelling mistakes, English ain't my first language.
