Balancing Emunah and Hishtadlus in Dating

Question: How are we supposed to balance our Hishtadlus with our Emunah specifically in regards to dating? I know that everything comes from Hashem and He knows what is best for me so how much work am I supposed to put in. Additionally, is it okay to daven for a specific person to be your Zivug or should the Bakasha be a more broad one?
