The human brain is a really weird, dysfunctional, thing. Often we know the answers to questions but we can't pull them out of our brain for love nor money. The key, sometimes, is actually asking a different question.
When i'm working on a track i'll sometimes find it difficult to know what the track needs. I can listen to it and not really understand where to go when I ask "What is the track needing?". Instead what I now try to do is instead ask "Is the track actually done?". If the answer is no then I start finding it easier to point out what makes the track not yet done. Its a shift from thinking about what my next step is to thinking back from my end-point and looking at what the scope of the gap is. For me it works and I can answer the second question much easier than the first. As an aside I also find that thinking in this way actually allows me to work for longer periods of time on a track without getting distracted. This simple loop of assessing whether the track is done often sparks my desire to immediately do the action I come up with there and then, making the move towards the finished track.
