[H] Terran in need of help

Hello! I am a new member of the day9 forums and I started play sc2 not too long ago. I am still in bronze and I am not sure how to improve. I keep hearing "dude you must have a good build" or "your timing must be perfect" but whenever I look for build orders I keep getting weird sites in google which don't have anything on them. Any help or tips are appreciated :).
