First of all,quit calling it a game. Be yourself and learn that rejection is experienced by everyone on this earth. There is no shame in be rejected. Even the wealthiest and most famous people on this earth have experienced rejection. That is what helps us to learn how to be strong in life.
When you learn to be yourself, but take notice of the things she enjoys, you will have topics for conversation. Just don't be phony or try to act overly cool or goofy funny.

If you have a particular interest, pursue it so that you can meet others that have the same interests.
