In fact, its structure can be divided into 3 parts of a small symphony where there is an introduction - the start, development - the culmination and the finale - the epilogue. In the first part only a singer with guitar accompaniment. He promises himself about future changes that should  happen. The romance of the state of his soul is passed on to us and we trust the author. 

In the following verses in folk rhythms the singer invites the whole ensemble to support him in his aspirations. The slow live sound played in a beautiful arrangement takes us to the next parts of the work where the reefs with cascades of drum beats sound in energetic tones. 

The piano solo soothes for a moment before the final part where the author still promises to change himself. We don't know if whether those changes will take place because the song shows how everyone promises to change themselves in the first place and nothing happens in principle becouse this is only pretty words. The song has a deep philosophical meaning and we can even consider an ironic connotation. The lyrics and music of this single are beautiful. Great work.
