📰 Today's Edition

Let's face it: as a founder, your to-do list never ends. 

Your inbox is overflowing. Your team needs decisions. Investors want updates. And that's just before lunch.

Most productivity gurus won't tell you: you will never complete everything. Not today. Not tomorrow. Not ever. And that's perfectly okay.

The most successful founders are the ones who've mastered the art of strategic incompletion – deliberately choosing what NOT to do.

This is where the 80% Rule comes in.

What Is the 80% Rule and Why It Matters

The 80% Rule is refreshingly simple: elite founders operate at roughly 80% capacity on purpose.

Yep. And it's not because they're slacking off. 

When you consistently run at 100% capacity – pushing yourself to the absolute limit day after day – you leave zero margin for the unexpected.

And in startup life, the unexpected isn't just possible; it's guaranteed. You’ll always fight fires.

If your calendar is packed wall-to-wall with meetings and your to-do list requires superhuman effort to complete, what happens when a critical customer threatens to leave?

Or when a key team member quits unexpectedly?

Or when a major competitor makes a surprise move?

You break. 

You either drop important balls, deliver subpar work, or push yourself into burnout territory – and that's not gonna help you or your company in the long run.

The 80% Rule gives you a crucial buffer. It ensures you have the mental bandwidth, emotional energy, and literal time to handle the fires that inevitably flare up.

The Psychological Cost of Perpetual Overload

Running perpetually at maximum capacity doesn't just impact your ability to handle crises – it fundamentally changes how your brain works.

When you're constantly overwhelmed, your thinking narrows. Your creative problem-solving abilities diminish. Your decision-making quality plummets faster than a hippocorn’s blood sugar.

You shift from strategic thinking to survival thinking.

You ever noticed how hard it is to come up with innovative solutions when you're exhausted and stressed?

That's your brain overloading.

When you're running on fumes, your brain prioritizes immediate threats and quick fixes over thoughtful analysis and creative solutions.

But, your most valuable contribution to your company isn't completing tasks – it's your ability to think clearly, see opportunities others miss, and make good decisions under pressure.

Identifying Your "Must-Not-Drop" Priorities

Not all fires need your attention. The secret to making the 80% Rule work is ruthless prioritization (remember The Eisenhower Matrix we chatted about a few months ago?).

Every founder has three types of responsibilities:

1. Critical functions only you can perform

2. Important tasks that could be handled by others

3. Busy work that feels urgent but adds minimal value

Most founders spend way too much time on categories 2 and 3, leaving insufficient energy for category 1 – the work that truly moves the needle.

This isn’t about accomplishing a to-do list but rather thinking about what is the next step you need to make that will 10x your business.

When you identify your true "must-not-drop" priorities, you gain the freedom to let other things slide when necessary.

Strategies for Implementing the 80% Rule

So how do you actually put the 80% Rule into practice? Here are some tactical approaches that have helped countless founders:

1. Time-block your "white space"

Literally schedule 2-3 hours of unstructured / no meeting time in your calendar every day. Protect this time as fiercely as you would a meeting with your biggest investor. This isn't "free time" – it's your buffer for handling unexpected issues or deep thinking work.

When nothing urgent comes up, use this time for strategic planning, creative problem-solving, or simply recharging your mental batteries.

2. Practice delegation

Ask yourself: "Am I the only person who can do this task?" If the answer is no, find someone else to handle it.

Yes, they might do it differently than you would. Yes, it might take longer to explain than to just do it yourself.

Do it anyway.

Your job as a founder isn't to do everything yourself – it's actually the opposite. You need to build a machine such that the company can run without you most of the time. 

3. Set boundaries around communication

You don't need to be available 24/7. Establish clear expectations around when you'll respond to messages and when you won't.

This might mean:

• Checking email only at specific times of day

• Using "do not disturb" features on your devices

• Creating an emergency protocol for truly urgent matters

• Batching similar communications together

Your constant availability trains people to expect immediate responses, creating a cycle of interruption that destroys your productivity.

4. Learn to say "not now" (instead of "no")

When new opportunities or ideas arise, avoid the binary thinking of yes/no. Instead, get comfortable saying "not now."

This preserves relationships and keeps doors open while protecting your bandwidth for current priorities.

5. Schedule regular recovery time

Even at 80%, founder life is intense. Build in regular periods for complete disconnection – whether that's weekends, evenings, or periodic vacations.

Your brain needs downtime to absorb what you’ve learned, spark new ideas, and recharge. The best founders see rest as part of their strategy, not a luxury.

Overcoming the Guilt

Let's address the hippocorn in the room: guilt.

Many founders feel intensely guilty about not completing everything on their plate. They see unfinished tasks as personal failures rather than strategic choices.

But the right way to think about this is that you're succeeding at strategic prioritization.

The 80% Rule isn't a magic bullet.

It takes a mindset makeover to pull this off in startup worlds that worship the grind. But for founders in it for the long haul, it’s the difference between burning bright and burning out.

Stay sparkly,
