theres this girl at scool that i like and i get really nervous around here i dont know what to say or how to start a conversation up with here we small talked a couple of times, and i think she might like me because of how she acts and she always gives me a little smile but i just never know what to say because im a really shy individual.

so my questions are as follows .
Whats a good way to start a good coversation and how do i keep that conversation goin?( this is the part im really bad at).
How can i tell if she likes me back?
what are the signs i should look out for if she does/doesnt like me?
how/ when should i ask her out if i thimk she likes me?
were should i take her?
and what are some good conversation tips.  (i cant stress this enough because this is were i always faulter.
and if she does go out with me how do i get her to find me interesting and not apear stupid?
I appreciate any and all advise but please, if all ur ganna write is "oh, just be yourself", then please dont write nothing. ive heard that more times than i can count and believe me that doesnt work because  ive tried(extreme case of shy!!!!)
