Pretty much in the beginning $rim is talking about how he accomplished so much more than he thought but he’s still the same person but more evolved. In the chorus, Ruby and $crim are saying how time will go by so fast so it’s pretty much saying “do things while you can”. Ruby in his verse is saying how he wish he did some things in his past while he could. He has done so much already so when he’s done he’s ready to “rest”. He deserves it. Both of them do. Ruby is also saying how pretty much nothing will change with how things are in the world. (like things are same old, same old). And how things were fun before they became bad.
