Songs about changing your life?
%26quot;My Old Ways%26quot; by Dr. Dog is pretty good. The music video is %26quot;cute%26quot;, also.

Probably not the genre you're looking for, and I could suggest stuff that is more in your genre but it's always good to try something new.
I find this song compelling.
