Day 39 of 75 Hard: The Discipline of Scheduling What Matters

Somewhere around day 30, something shifts.

When you start the 75 Hard Challenge, it feels like a test of willpower. A battle. A grind. Drinking a gallon of water feels like an impossible task. Two workouts a day seems unsustainable. Reading every single day? No way I have time for that. But by day 39, you realize something: It’s not about the challenge. It’s about who you become because of it.

Discipline changes everything.

It’s not just about fitness. It’s about clarity. It’s about eliminating the noise. It’s about simplifying the path forward. And for me, it has completely reshaped the way I think about time, scheduling, and what truly matters.

Building a Product is Hard—So Is Becoming Someone Who Can Build It

Every single day, I do a 10K run. Every single day, I schedule it in CalnFlow in just a few taps. Not because I need a reminder—I won’t forget. But because the act of scheduling reinforces the commitment. It’s a promise to myself.

And that’s what scheduling really is. A commitment. A declaration that something is important enough to take up space in your life.

Building CalnFlow has been its own version of 75 Hard. It’s demanding. It forces me to push through resistance. It requires ruthless simplicity. Every feature, every flow, every pixel—I ask myself: Does this make it easier for someone to schedule what’s important to them?

Most scheduling apps focus on availability. Open slots. Logistics. But CalnFlow is about energy. About action. About making it effortless to book what matters before life fills up with distractions.

How I Work (And How CalnFlow Helps Me Do It)

• I go to bed early.

• I wake up in the middle of the night for deep work sessions.

• I rest when I need to.

I don’t follow a traditional schedule. I follow my energy. That’s why CalnFlow’s Schedule Now feature is so important to me. It lets me book things when I feel the momentum without friction. One tap, and it’s on my calendar.

Some days, my morning run is at 8 AM. Some days, it’s at 10:30 AM. I don’t stress about locking in a time—I just schedule it when I am ready. That’s what makes it work.

The Hardest Part Isn’t the Workouts—It’s the Water

For most people, the toughest part of 75 Hard isn’t the workouts. It’s drinking a gallon of water a day. You think you drink enough water until you actually start measuring.

The same is true for time. You think you use it wisely until you actually track it.

The best part of this challenge isn’t the physical transformation—it’s the awareness. You become brutally aware of your habits, your excuses, and how much of your day is lost to things that don’t matter.

And that’s what I keep thinking about while building CalnFlow.

How do we eliminate friction? How do we remove the invisible time-wasters? How do we make scheduling what you love as easy as possible?

Lightning Mode is Coming

If 75 Hard has taught me anything, it’s that speed matters. The faster you commit to an action, the more likely you are to follow through. That’s why I’m rolling out Lightning Mode in CalnFlow very soon.

It’ll make scheduling even faster. Less friction. Less thinking. More action. Because when something matters, the last thing you want is an extra step slowing you down.


If I schedule runs, meditation, workouts, reading, writing, and yoga. It needs to be fast. Lightning fast. No typing, just taps.

39 Days Down. 36 to Go.

The real value of 75 Hard isn’t in the challenge. It’s in who you become because of it.

The same is true for building something great.

Most people don’t fail because they aren’t capable. They fail because they don’t commit. They let distractions win. They think too much instead of acting.

39 days in, I’ve learned that discipline isn’t just about fitness. It’s the foundation for everything. Your schedule. Your work. Your habits. Your ability to build something people love.

And that’s why I’ll be running again tomorrow. Scheduling it. Showing up. And simplifying everything along the way.
