What’s the easiest way to repair my credit score when I’ve already eliminated my bad debt?

I screwed up years ago as substantially as I’ve already paid off those intense credit adjudge debts. The usually debts we owe right absent have been the tyro loan (always paid upon time), the brand newborn credit adjudge (paid upon instance as substantially as usually used for emergencies), as substantially as the automobile remuneration (paid upon time).
How do we intend my credit measure to go up?
