Lesson 1 of 4

The Two-Minute Rule

David Allen's getting-things-done principle: if a task takes less than two minutes, do it immediately. Don't schedule it, don't add it to a list, just do it now. The rule eliminates the mental overhead of tracking dozens of tiny tasks that accumulate into cognitive clutter. Capture big tasks; eliminate small ones instantly.

Source Allen, D. (2001). Getting Things Done.

Parkinson's Law

Work expands to fill the time available for its completion. Give yourself a week to write a report and it will take a week. Give yourself two hours and it will take two hours. Deadlines don't just create urgency, they reveal the minimum viable effort. The cure for Parkinson's Law: always constrain your time.

Deep Work vs. Shallow Work

Cal Newport divides work into two types: deep work (cognitively demanding tasks requiring full focus, writing, coding, complex analysis) and shallow work (email, meetings, admin). The paradox: modern workplaces optimize for shallow work, constant availability, open offices, Slack pings, while deep work is what actually creates value.

Source Newport, C. (2016). Deep Work.

Quick quiz

You have 8 hours in the office. You spend 6 hours in meetings and on email, and 2 hours writing a strategic plan. According to Cal Newport, which block produced the most value?

Lesson 4 of 4

Eat the Frog

'If it's your job to eat a frog, it's best to do it first thing in the morning.' The line is often credited to Mark Twain, with no record that he said it. The frog is your hardest, most important task, the one you're most likely to procrastinate. Do it first, before email, before social media. The rest of the day feels easier once the hardest thing is done.

Source Tracy, B. (2001). Eat That Frog!
