You can’t out-tough a broken plan. Sometimes resilience means changing the plan.

Effort cannot repair a design fault. If the schedule was never going to fit, or the method does not work, adding determination produces a more exhausted version of the same failure. There is a strong pull to treat every shortfall as a shortfall of will, because that feels more honourable than admitting the plan was wrong. Changing it is the harder move and the more useful one.

Ask of the thing you keep failing at whether the plan is actually possible. Count the hours it needs against the hours that exist. If the arithmetic does not work, fix the plan rather than promising yourself more discipline.
