You gain power the moment blame stops being more important than solutions.

Blame and problem-solving compete for the same attention. Every minute spent establishing whose fault it is buys you nothing toward the outcome, and it usually hardens the people whose cooperation you need. The moment you release the need to settle the ledger, options reappear that were there the whole time.

In the next difficulty, try asking what would improve this rather than who caused it. Keep the accountability question for later if it still matters. You will notice how much faster things move when nobody is defending their record.
