Thank you for the kind words and I am glad that the videos have been helpful to you.
A good way to start talking to this girl is by simply finding something in common with her to start off with.
You could talk to her about a class that you both share and ask her a question or an opinion in reference to something that was recently taught.
Proceed to talk to her as often as you can when you encounter her in class.
Start the process of building rapport with her by bringing up topics around feel-good topics such as music or even pop culture.
You should ask her out not so long after you have established a decent amount of rapport with her.
You will often know when this is if you notice that she is beginning to tease you or flirt with you.
