For me, have that positive feeling. Hold on to your feelings to that someone first. Keep it first. Better to know the attitude, the background, the whole characteristics and everything about the one you like. It's better to know first than to regret in the end. And when the time comes, its the time also to tell your feelings to him. Have a strong courage and positive thought when you are going to tell your feelings to him. And keep in your mind that whatever answers you get from him be positive.
