Weekly I/O is entering a new chapter

Hi friends,

When I started Weekly I/O, it was simply a way to digest my own learnings. I never imagined it would resonate with so many people.

This project has been growing fast recently. After 465 learning inputs, Weekly I/O is ready to take the next step, and I'd love for you to join me on the journey.

Weekly I/O is adding a paid subscription plan!

To thank you for being an early supporter, I’m sharing the biggest discount upfront:

Subscribe in the next 72 hours to get 45% off your first year, just $48 for the entire year. (You save $40 off the regular $88 annual subscription.)

If you've already pledged at the previous $80/year subscription plan, this early thank-you discount will be automatically applied. Thank you so much for believing in me and showing your support from the start. It truly means a lot to me!

What’s Changing?

Starting with the next Weekly I/O:

Paid Subscribers will:

• Continue receiving Weekly I/O every week

• Enjoy early access to longer, in-depth articles when I publish them

• Have access to all the Weekly I/O archives

• You really support and feed me and help make Weekly I/O even better

• I want to say thank you again here 😊

Free Subscribers:

• You’ll still get the newsletter, but it’ll switch to a monthly frequency (Maybe the free one will be called "Monthly I/O" 😂)

Why Subscribe?

In under 10 minutes of reading each week, you’ll get at least one valuable idea that resonates with you. Something like:

One actionable heuristic to help you make better life decisions:

• Young & Old Test

• Region-beta Paradox

• Why to Buy

• Luck and Arena Razors

One practical theory to level up your work:

• Fogg Behavior Model

• Knowledge Pyramid

One interesting phenomenon to entertain you:

One scientific finding to help you better understand the world:

One inspiring idea to help you become a better person:

• Happiness as Income

• Hanlon's razor

• Locus of control

• Laugh at Fear

My goal is to help you (and myself) better understand the world and live a more fulfilling life. Essentially, you will get the distilled version of what I learned towards that goal!

What will it cost?

$88 per year, or $8.8 per month.

I hope that each year, at least one idea from Weekly I/O will meaningfully improve your life, making your subscription easily worth it.

If cost is a barrier, please send me an email and we'll figure something out together. I don't want the price to be a financial stress for anyone, and I’m committed so we can continue learning together.

Special Thank-you Offer: Subscribe in the next 72 hours, get the first year for only $48 (45% off)

It's been incredibly rewarding receiving the love and feedback you share about Weekly I/O:

"I GAINED A LOT OF KNOWLEDGE FROM YOUR SHARES."

"I look forward to them - always useful and interesting content."

"I am so surprised that you can keep sharing such interesting concepts, theories, or models with your readers."

"There is actually nothing compared to the treasure of knowledge you share."

"I still remember the content of the Ackerman model you shared last week, and I think it is really useful. That framework gives us some tips to follow to make us become better negotiators."

Best,
