Practices that may help
- Use reference class forecasting for project estimates
Estimate how long similar projects have taken historically before estimating your specific project.
Base-Rate Neglect: Why We Ignore the Odds - Run a pre-mortem from the outside-view perspective
Imagine the project has failed — then ask which base-rate failure type caused it.
The Outside View - Schedule buffers as first-class commitments
Add explicit slack time to your schedule and treat it as non-negotiable white space, not a reserve to fill.
The Planning Fallacy — Why Your Estimates Are Always Wrong - Ruthlessly edit projects in progress
Cut content, scope, or steps from anything in progress that doesn’t serve the core goal.
Essentialism: The Art of Eliminating the Non-Essential - Run a premortem before committing
Imagine the project has already failed and work backwards to find why.
The Planning Fallacy — Why Your Estimates Are Always Wrong - Run a project-level Pareto analysis quarterly
Every quarter, analyze which projects generated 80% of your meaningful progress and let that drive next-quarter commitments.
The Pareto Principle: 80/20 for Personal Productivity - Reference class forecasting
Before estimating, look up how long similar past projects actually took — not how they felt.
The Planning Fallacy — Why Your Estimates Are Always Wrong - Keep each project’s Action Steps physically separate from other projects
Mixing action steps from different projects in a single list increases context-switching cost and makes progress harder to see.
The Action Method, Made Practical - Invoke the outside view before committing to any significant plan
Before finalizing a plan or forecast, ask "How did similar things go?" as the first checkpoint.
The Outside View - Identify the right reference class for your situation
Find a well-defined set of past situations that are structurally similar to yours and collect their outcome data.
Reference Class Forecasting
Does this sound like the set of challenges you might be facing?
- I’m putting a timeline on this project from the plan in my head, and it always feels doable
- I’m all-in on this plan and can barely make myself imagine it going wrong
- I pack my day back-to-back with no gaps, so the moment one thing runs long or something unexpected pops up the whole rest of the schedule collapses like dominoes and I’m behind on everything by noon.
- This thing I’m building keeps swelling
- I’m about to commit to this timeline and on paper it all looks fine, but I have a nagging feeling I’m glossing over the ways it could go sideways because admitting them now feels like talking myself out of it before I’ve even started.
