Which way is God Leading Me?

This is a question that I have been asking myself for a while now. I feel like I am at a crossroads and can't move on until I know which way to go.

The other night I went to a friend's house and used my Satnav to get there. The little box got me almost there but not quite, I was just one street away from where I should have been.

What I don't want to do is act and move before definitely knowing God's next step otherwise I could end up," one street away" from God's will for my life.
