My Life-Changing 13-Year Odyssey in Note-Taking and PKM

My Life-Changing 13-Year Odyssey in Note-Taking and PKM

A thread embark on a journey of discovery and reflection on note-taking and Personal Knowledge Management (PKM).

Join me as I share insights from my experiences.

First, a little bit about me.

My journey began with an MSX computer when I was 8, and it evolved through various roles in tech and business.

I've worked at 5 big corporations and created my first company at the age of 26. Now, running four.

September, 2020: Roam Research: The Change of Model

A cornerstone, introducing me to the concepts of outlining and back-linking.

What am I supposed to do?

That was my thought at that time staring at that minimal daily note page.

First approach to 2 concepts we've deeply developed, later on, at the Paperless Movement® in our ICOR® methodology related to the thinking process of information: Deep Thinking and Shallow Thinking.

From rapid information processing to in-depth analysis.

September, 2020: Notion, a pivotal moment

I developed my own comprehensive productivity system.

It went beyond mere note-taking and PKM, blending information and action in a cohesive way.

However, I soon realized the limitations of a “one app fits all” approach.

May, 2021: Obsidian, the perfect tool?

I tried to make it (again) a one-size-fits-all solution, combining information and action in one app.

This was my second and final failure in such an attempt, a lesson I've truly learned this time.

Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

Sean Green

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Shankul Varada

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Ghazala Begum

Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.

Giovanna Scalzone

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
