Separate real deadlines from preferences
A true deadline has a consequence or dependency. A preferred date can still matter, but should not crowd out genuinely time-sensitive work.
Look at value and consequences
Ask what outcome changes if the task is completed or delayed. This reduces the influence of novelty and inbox order.
Respect capacity
A priority list longer than the time available is not a plan. Reduce the daily commitment to the amount you can realistically execute.
Use dependencies
Sometimes the highest-leverage task is the one that unblocks several later tasks or another person.
