Low effort high sentence crime like credit card or check fraud. Represent yourself in court and be a complete ass to maximize the jury’s dislike of you, no sob stories reveal zero empathy for what you did. Try to find that sweet spot between minimum security prison, but long sentencing. Make a friend in jail and start a “fight” with them the day before your probation hearing or something to extend the behavior without angering the guards/warden too much?

It’s a pretty high risk low reward strategy, but the risk is mostly because it’s hard to get into a “good prison”. Also make sure you do it in a state with free prison, some states are pay-to-stay prison, though I guess that could open the opportunity for loan fraud and another sentence if you do get out?
