His own little world is breaking down because she is gone and he can't and won't hold his feelings back. This time rain, which is always associated as something sad, as if the clouds would cry. He always associates the places he travels to with weather. He starts his travel and missed his train. 'I missed that train, New York city - it rains! She kind of shows him that she don't think this relationship is getting fixed but he can't let her go. But at the same time he is asking himself if there is even something to fix and if she wants this relationship still as well. He kind of wants to fix things ,which go terribly wrong in their relationship, with her. So let's start with the analysis of the lyrics. He is doing trips to different areas (but I will come to that later specific) and tries to forget her but it is just not working out. The song 'Mind over Matter' from Young the Giant is (for me) about a man who just broke up with ,for him, the love of his life.

I also think that there isn't ONE specific interpretation for songs since they tell so much and everyone is keeping it in differently. Well this is my personal interpretation to this song.
