Well... oraund my school there's this girl that I like so much I can stop thinking about her. The problem is I don't know how to start talking to her. Sometime I fell like going up to her or writing a not or even telling my friend who knows her to tell ger how I fell... what should I do

Go to her and ask to take her out, but do not use the old strategy to ask a girl out. Be modern, create an ice breaker, make her laugh a little or smile, get the number, call her in the evening, then ask her out... These are the basics
