Does your car insurance cover what really matters?

Not all car insurance is created equal. Minimum liability coverage may keep you legal on the road, but it often won’t be enough to cover the full cost of an accident. Without proper limits, you could be left paying thousands out of pocket. The right policy ensures you and your finances are protected. Check out Money’s car insurance tool to get the coverage you actually need.

Last email for 2025

This is the last day of 2025, and it's also my last letter to you.

2025 was a year to remember, most probably the most thrilling year so far.

I went through every emotion. Let me share everything with you!

What bothered me the most

AI is taking over the world day by day, and people are becoming too dependent on it. That is a serious issue.

Whether it is writing, designing, or automation, AI is everywhere.

Everyone is writing with AI. Everyone is designing with Nano Banana. Everyone claims to be an AI agent expert.

The main issue is not AI. The actual issue is how people are using AI.

Humans are known for their ability to think critically. But after the arrival of AI, many have stopped thinking deeply. They are producing half-baked work and calling it output.

People are becoming blind in their dependence on AI. The real impact will be visible after 10 to 15 years. Compared to that, job loss is still a very small issue.

Reflection

Personal level

Device:

My 2025 started like any other year. But this year, I bought a Mac and an iPhone, which is a dream for many.

I never specifically dreamed of owning Apple devices. What mattered more was having the ability and opportunity to buy tools that support me in this journey of becoming someone.

And for that, I am grateful.

Travel:

This year, I travelled to

  1. Humayun’s Tomb (Delhi)

  2. Chopta, Tungnath (UK)

  3. Lonavla, Juhu beach (Pune, Maharashtra)

  4. Varansi (UP)

Finance:

This year, I made 3,47,943 and spent 5,10,287.3

Loss of - 1,62,304

Health:

I was unhealthy most of the time of the year. Mostly suffered from cold issues.

Personal:

I’ve failed in most of them. I wanted to achieve time and location freedom, but I couldn’t get it. Also, set book reading goals of at least 12, but I could only read 7.

Business:

I registered my business as an OPC under the name Contentanirban Ventures OPC Private Limited.

I started the year with Dark Chocolate, Alivewithad, and my personal email marketing service.

In February 2025, I launched The Email Show, which I later rebranded into The Growth Flywheel podcast.

In May, I sold Dark Chocolate for $80. Around the same time, I also started Trimmerly and later Insideletter.

Trimmerly began as a podcast agency. I then shifted it to video and, in 2026, I am focusing fully on YouTube. I worked with only two clients through Trimmerly, but it taught me a lot.

Insideletter started as a place to share my learnings about newsletters. After several changes, it will move to a curation-based newsletter in 2026.

alivewithad was rebranded to Rentless and evolved from a personal newsletter into a dedicated travel newsletter brand.

2025 was a year of experiments, pivots, and lessons. And I am carrying all of that forward.

Next year's goals

I sat on the 25th and decided what I’ll not do more than what I’d do in 2026.

Business-oriented:

  1. Insideletter - My main venture, a newsletter for newsletters. Distribution channel LinkedIn and X. (Reddit and YouTube as the secondary)

  2. Undelivered - My personal newsletter. Distribution channel X and IG.

  3. Rentless - My travel newsletter. Distribution channel IG and YouTube.

  4. Growth Flywheel - Podcast-led brand. Distribution on YouTube and IG.

  5. Trimmerly - My YouTube agency. Need to plan a lot for this to get clients and make money.

I will focus more on consulting work because I do not want to build a service-based business. It is tiring.

Personal goals:

I plan to travel to 5 foreign countries: Nepal, Sri Lanka, Vietnam, Laos, and Cambodia.

Mileswithad: My personal travel brand. I will do travel vlogging in Bengali and create content on Instagram as well.

I want to start writing my book, which I planned to begin in 2025.

My goal is to create multiple revenue sources.

Beyond work, I want to become financially free, get fitter, and eat better.

Thanks for being here 🙂

I want to say thank you to you for reading my newsletter and for being with me throughout the year. I truly appreciate you. You are amazing.

Enjoy your time. Let’s say a warm goodbye to 2025 😊
