Maybe it’s not God’s Will that someone is struggling financially; maybe it’s that they are not following the command to tithe? (Choosing to rely on yourself means choosing to be cared for by . . . you. And then you miss out on the blessings that come with relying on and being cared for by God.) Maybe it’s not God’s Will that someone loses their job; maybe they haven’t been putting their best effort into it, doing their job for the glory of God? Maybe it’s not God’s plan for someone to follow a certain path; maybe they didn’t really bother to ask for God’s guidance and to wait for God to guide them? And when He did show them what they were to do, maybe they didn’t obey? Maybe it's not that God gave us the short stick; maybe it's that we are failing to live life His way?
My concern here is that it’s far easier for us to call all things “God’s Will” than it is to realize that we have an enormous impact and influence on what happens. If we were to realize that God just doesn’t do what He wills, but that we have an impact and influence on what happens, then we would have to take more seriously our responsibility to search for God, to remain close to Him, to seek righteousness, to be obedient, and to pray. (Wow, I bet that you are hating the redundancy by now. But, oh, how important these things are. And yet, how seldomly we care about them.)
