Quick heads-up: Kanishka’s Archive’s the same. I’m just tweaking the format so every week you get the best, most useful stuff- nothing extra.

anyhoo…

I hit a PR in the gym three months ago, I spent the entire week chasing another one, and ended up hitting lifting PRs every day that week. After that, I shifted focus and spent the next month and a half training for my first 13-mile run. Both require completely different diets and workout plans.

I was moving so fast I forgot what was around me.

Here's what I've learned studying how the best builders work: They move fast because that's where the magic lives.

Speed compounds.

Let’s dive in.

A common belief is, speed and quality are opposites. They're not.

Speed creates feedback loops. The faster you move, the faster you learn. The faster you learn, the better your decisions become.

Slow is expensive.

When you take too long to decide, you're gathering doubt.

The people who win don't have perfect information. They have fast iteration cycles.

John Boyd was a fighter pilot in the 1950s.

He studied something strange: the F-86 kept beating the MiG-15 in dogfights, even though the MiG was objectively the better aircraft. Faster turning. Higher climbing. Better frontal visibility. But the F-86 won 9 out of 10 times.

Boyd figured out why: the F-86 had a hydraulic flight stick. The MiG-15 had a manual one. Moving the MiG's stick took slightly more physical effort. Not much. But enough that after each maneuver, the MiG pilot got a little more fatigued.

Each iteration slowed down by milliseconds. Those milliseconds compounded. The MiG pilot didn't lose because he got outfought. He lost because he got out-iterated. Boyd called it the OODA Loop: Observe, Orient, Decide, Act.

The pilot who cycled through decisions fastest won—not the one with the better plane. The same holds in business. A study of 318 CEOs (1996–2000) found that faster strategic decision-making reliably predicted later growth and profitability (If you’re chronically online, you already know this still holds in 2025 and will only matter more as AI scales).

Most companies and people still treat every decision like it's irreversible, but 80% of decisions are two-way doors. You can undo them.

The cost of being wrong? Small. The cost of being slow? Massive.

This week, apply the 48-hour decision rule.

For any reversible decision, give yourself 48 hours max. Not to think. To decide and act.

Here's how:

1. Write down the decision

2. Ask: "Can I undo this if I'm wrong?"

3. If yes, decide within 48 hours

4. Move and track what happens

Most of what you're sitting on right now is reversible. You're not waiting for clarity. You're gathering doubt.

Your decision-making is chemical.

Cortisol peaks naturally around 8-9am and 12-1pm. That's your body's built-in alertness. Drinking coffee during those windows wastes it.

You're already alert.

The move? Delay your first coffee to 90-120 minutes after waking.

Let cortisol do its job. Then use caffeine when energy dips, around 10am or 2pm.

You'll make faster, sharper calls when your brain chemistry works with you, not against you. I avoid caffeine after 2 p.m. on most days.

Speed is about building a system where you can move fast and learn faster.

The people who look decisive aren't braver. They just know which doors swing both ways. This week, find one decision you've been sitting on.

Give yourself 48 hours.

Move. What’s the worse that could happen?
