Hello! 👋
This intro is going to be longer than usual, but it’s worth reading.
I’m not sure if it should be an announcement or an update or something else, but there are changes coming. Good ones! 👌
Long story short, during my time off this summer, I was thinking about what to do next.
And I decided I’d like to start writing about “thriving on the internet.”
📌 So we’re going to give this newsletter a remake!
From making money, to running a solo business, launching side businesses, running an agency, using online tools, my experiences and lessons.
IMPORTANT:
I’m not going to sell courses, quick wins, cash grabs, etc.
I’ll share only what worked for me, what I did, and what worked for the people in my circle.
I’m about to turn 35. In the last 10+ years, I’ve earned more than €650,000 in profit. I have an apartment, a few cars, investments, no debts or loans. I’ve visited nearly 50 countries.
I’m not bragging, but I think it’s an achievement for an Eastern European guy who started with €0, born in a village of 250 people.
I’m working from home, on my own schedule, at my own pace, and everything depended on me.
I was earning more than I could earn at a full-time job here in Lithuania. All that freedom, traveling, exploring, meeting people, and learning is something I’d like to share with you!
So what’s next, and what’s changing?
Sunday issues aren’t changing! Each Sunday you’ll get a newsletter with the latest tools, apps, and other cool stuff, like before. Nothing changes there at all.
Starting September 1st, I’m changing the name of the newsletter from “Insanely Cool Tools” to simply my name, “Justas Markus.” Again, I want to make it more personal.
Also, starting September 1st, you’ll receive one extra issue in the middle of the week. Long-form, deep-dive content on different topics, covering making money, starting online, side businesses, etc. More info on September topics - next week!
All the content during September will be free. I plan to share 4 great issues, so you’ll have a month to decide if you like it. After that, this type of content will be behind a paywall. But again, Sunday’s newsletter stays free for everyone.
Probably you’re thinking of that 👆
Yes, after September, that new segment will be paid. Why? Because I’ll be sharing what took me years to learn, all the long nights, failures, financial mistakes, etc.
I’m not going to try to convince you now. You’ll receive 4 free issues in September, and then you’ll be able to decide. 🤝
I’m already working on the issue about “making money with newsletters.” I’m not even halfway through and already spent 15+ hours on it.
From how to start or buy a newsletter, to how to grow it, best materials, tips and tricks.
Sounds like a random topic, but last year, my 2 newsletters earned me nearly €40,000 in profit with just 2-3 hours per week of work.
And trust me, people are making insane money with newsletters.
After that, we’ll have many other topics on how to start your independent life and move forward toward the freedom you always wanted. 🏝️🍹😎
I hope you liked the news, I’m looking forward to it! 😛
