I feel like this song is a message to everyone else based on his experiences. From what I have heard he was told that he had until a certain age to try to live out his dream but if he couldn’t he would have to go to vocational school had he ended signing with a label like 3 months before. I think what the song is saying is don’t give up on yourself no matter how far out of your grasp what you want seems. Keep trying your best no matter what and don’t sell yourself short for anything.
