Welcome to Stacked #001

The best information in AI, business, health, and money is out there — but it's buried in 47 podcasts, 200 tweets, and a bunch of newsletters written for people who already know everything.

You're not here for that. You want the cheat codes — simplified, no jargon, ready to use today.

Every Monday, I dig through the noise so you don't have to. Let's get into it.

AI Drop: ChatGPT Just Became an Ad Platform

If you use ChatGPT for free or on the $8/mo Go plan, heads up - OpenAI just started running ads inside your conversations. Paid tiers like Plus and Pro stay ad-free, but everyone else is now seeing sponsored content mixed into their experience.

Why this matters to you: the tool 200 million people use every day now has advertisers in the room. OpenAI says ads won't influence your answers and they'll be clearly labeled, but let's be real - when money enters the picture, the incentives shift. The space where you go to think just got a little noisier.

This is actually part of a bigger trend. AI tools are expensive to run, and companies need to make money somehow. Free tiers are going to get more cluttered across the board. The people who pay for their tools will get a cleaner, faster, better experience. The gap between free and paid AI is about to widen fast.

The move: If you use AI for anything serious - work, research, business decisions - this is your sign to either upgrade to a paid plan or try an alternative that doesn't run ads. Claude by Anthropic is my go-to with no ads, no clutter, just a clean workspace. Treat your AI tool like your workspace, not your social media feed.

Business Move: The Side Hustle Nobody's Talking About

AI workflow consulting just quietly became one of the most in-demand side hustles of 2026. Here's why: most small business owners know AI exists. Almost none of them know how to actually use it.

Think about your local dentist, your realtor, your gym owner, the restaurant down the street. They're drowning in admin work - scheduling, follow-up emails, social media, invoicing - and they've heard AI can help. But they don't have time to figure it out, and they're not about to watch a 4-hour YouTube tutorial.

That's where you come in. If you've spent any real time with ChatGPT, Claude, or automation tools like n8n or Zapier, you already know more than 90% of local business owners. That knowledge gap is where the money lives. People are charging $50-150/hr for this, and according to multiple 2026 side hustle reports, demand is only growing. Pro tip: n8n is my go-to for workflow automation - it's open source, more powerful than Zapier for custom builds, and has a free self-hosted option. If you're serious about offering this as a service, learn n8n first.

The move: This week, reach out to three local businesses and ask one question: "What tasks eat up most of your time?" Then show them how AI can handle it. You don't need a degree, a certification, or a website. You just need to know more than the person across the table - and right now, you probably do.

Health Hack: It Takes 66 Days, Not 21

You've probably heard it takes 21 days to build a habit. That number is made up. A study published in the European Journal of Social Psychology tracked people forming new habits and found it actually takes an average of 66 days for a new behavior to become automatic. Some habits took as long as 254 days.

That's not meant to discourage you - it's meant to stop you from quitting on day 25 thinking something's wrong with you. Nothing is wrong with you. You just haven't hit the threshold yet. Every time you "failed" at building a habit, you probably just stopped too early.

The Washington Post recently highlighted this research and added a key insight: the people who succeed don't rely on willpower. They pre-solve their obstacles. They make the habit so easy to do that skipping it feels harder than doing it.

The move: Pick ONE habit you've been trying to start. Just one. Write down every single barrier that could stop you and solve each one before it happens. Too cold to run? Find a 30-minute YouTube workout you can do in your bedroom. No time to cook healthy? Frozen vegetables are nutritionally identical to fresh. Don't feel like going to the gym? Put your workout clothes next to your bed so they're the first thing you see. Remove the friction before it removes your motivation. Then give it 66 days (real days) before you judge yourself.

Money Play: Your Savings Account Is Robbing You

If your emergency fund is sitting in a regular checking or savings account earning 0.01% interest, you're losing money to inflation every single day. That's not dramatic - it's math. Inflation is running around 3%, which means your money is worth 3% less every year it sits there doing nothing.

Meanwhile, online banks are still offering around 4% APY on high-yield savings accounts. That's a 400x difference from what most traditional banks pay. The catch? This window is closing. The Fed cut rates three times in 2025, and more cuts are expected this year. Every rate cut means lower returns on savings. The time to lock in is now, not next month.

Here's what this looks like in real numbers: $5,000 in a regular savings account earns you about 50 cents a year. That same $5,000 in a high-yield account at 4% earns you $200. Over five years, you're looking at over $1,000 in free money - just for putting it in the right place.

The move: Open a high-yield savings account this week. Wealthfront offers around 4% right now with no minimums and no fees. Move your emergency fund there today. It takes about 10 minutes. That might be the highest-paying 10 minutes of work you do all year.

Quick Hits

Stuff that crossed our radar this week that didn't make the main four:

  • $650 billion. That's how much Google, Amazon, Meta, and Microsoft are spending on AI infrastructure in 2026 - combined. Amazon alone is putting up $200 billion.

  • Alibaba dropped RynnBrain - an AI model that helps robots understand the physical world around them. The robot revolution isn't coming. It's here.

  • Cutting social media to 30 minutes a day significantly reduces depression and loneliness, according to a study in the Journal of Social and Clinical Psychology. Set a timer. Your brain will thank you.

  • The 401(k) contribution limit for 2026 is $24,500. If you're over 50, you can add an extra $8,000. If your employer matches, contribute at least enough to get the full match - that's literally free money you're leaving on the table.

This Week's Stack

  • Claude — AI assistant

  • n8n — workflow automation (free, open source)

  • Zapier — workflow automation (easier, paid)

  • Wealthfront — high-yield savings

Stacked is brand new. You're here at the beginning. That means something to me.

If even one thing in this email made you think differently, do me a favor - forward it to one person who needs to see it. That's how we grow this thing. No ad budget. No algorithm. Just people sharing what's useful.

See you next Monday.
