I can't seem to make my story work with the Goal I have chosen.

If you are set on a certain Goal or Concern, yet it doesn't seem quite right, try it as the Benchmark. For example, in the Objective Story throughline, your objective characters may spend a lot of time over the course of the story gathering information (Learning), leading you to think that Learning is their concern or the Story Goal. Yet Obtaining may be the actual concern/goal, and the gathering of information is just the standard by which their progress is measured towards achieving the goal or solving the problem.
