The song "Je Commence Demain" by Jean-Jacques Goldman tells the story of a person who realizes that they need to make changes in their life in order to grow and become wiser. The lyrics convey a sense of self-reflection and the desire to break free from old habits and start anew. The narrator expresses the need to close off certain aspects of their life, metaphorically represented by "closing a fence" and "cutting wood." They also mention the importance of putting on a metaphorical "costume" and walking straight, implying the need to adopt a more disciplined and responsible approach in life. The chorus repeats the idea of becoming wiser and more reasonable at their age, acknowledging that they need to make changes. They recognize their current shortcomings and vow to start making the necessary changes from the following day. The lyrics further delve into the narrator's desire to leave their current path and put their guitar down in order to pay attention to what others have to say, before it becomes too late. This portrays a sense of acknowledging the need for a change in priorities and being more attentive to important matters in life. The song also touches on the narrator's longing for a stable relationship. They express the need to find a kind and nurturing woman, contrasting with their current involvement with other women that only stir up their emotions. Overall, "Je Commence Demain" conveys a message of personal growth, the recognition of the need for change, and the determination to embark on a new path towards wisdom and maturity.
