These are important questions, but sometimes they just aren't clear. I was walking and praying about this earlier this week in the woods near our church. For some reason, it is much easier for me to pray while walking outside than sitting still sometimes (imagine that). As I was walking I felt the Holy Spirit speak to me through my surroundings. Sometimes, the path of our life is about to turn, and though we cannot see exactly where it is going, we can see that it is turning ahead. We want to know where it is headed, but cannot because we are simply too far from the turn to be able to see. In these situations, we have to continue waling our path until the turn becomes clear.
