Mistake 1: Vague tasks
Symptom: You stare at the timer unsure what to do.
Fix: Rewrite the task until it fits one sprint: “email client” → “draft three bullet points for paragraph 2.”
Mistake 2: Skipping breaks
Symptom: Afternoon crash, headaches, resentment toward the method.
Fix: Breaks are mandatory. Stand up. If you “do not need” a break, you still take a micro-walk.
Mistake 3: Multitasking inside a sprint
Symptom: Tab chaos, nothing finished.
Fix: One task label per Pomodoro. Batch Slack into its own sprint.
Mistake 4: Changing intervals daily
Symptom: You never learn what works.
Fix: Hold 25/5 or 40/10 for five workdays, then adjust once based on data (completed sprints, energy).
Mistake 5: Punishing yourself for missed sprints
Symptom: You abandon the system.
Fix: Missed sprints are information. Shrink scope, protect mornings, try again tomorrow.
Mistake 6: Using Pomodoro for everything
Symptom: Timer during therapy, lunch, or creative wandering that needs no structure.
Fix: Pomodoro is for execution. Exploration and rest can stay untimed.
Quick audit
At week’s end, ask: How many Pomodoros did I complete? Where did breaks fail? One fix for next week only.
