10 Most Life-Changing Ideas I’ve Discovered after 700+ Posts

đđ Lifelong Learning & Deeper Development (Sloww Stage Support)
The first two ideas are related to: Sloww Stage Support (Lifelong Learning & Deeper Development): How do I develop by learning?
1. Adult Learning
This can be considered an umbrella idea for many concepts: living inquiry, lifelong learning, adult learning, transformative learning, synthesizing, interdisciplinarity, etc. While those concepts do have nuanced definitions, there’s a thread that seems to run through adult questioning to adult learning to adult development. This topic is extra impactful to me because I now understand that it’s how I seem to be wired and how I can give myself to the world. I describe myself as an independent, inquiring, interdisciplinary integrator (in other words, a “synthesizer”). It’s been such a big realization that it’s even the topic of my first online course.
Living Inquiry (or adult questioning):

2. Adult Development
Similarly, this is an umbrella idea that includes many concepts: adult development, human development, psychological development, vertical development, perspective transformation, etc. It has completely transformed how I view myself, others, and life itself. Of all the theories I’ve seen, Susanne Cook-Greuter’s “ego development theory” and Robert Kegan’s “subject-object theory” have resonated the most. Why? Because I didn’t discover them until after I had already gone through several “stages,” and it was incredible how closely my own lived experience matched the descriptions. Stage theories have their fair share of critics out there (see the Nora Bateston post below), but I’ve found learning about them to be a net positive in my life.

3. Slow & Simple Living
The discovery of the concepts of slow living, simple living, voluntary simplicity, and downshifting completely rocked my worldview. Prior to this discovery, I had no idea there were people out there intentionally choosing slower and simpler lives. These ideas I discovered in late 2015 and early 2016 planted the seed for all things Sloww.

4. Lifestyle Design
I’ve realized that much of intentional living comes down to lifestyle design. And, when it comes to lifestyle design, nothing has been more impactful for me than Jacob Lund Fisker’s work on Early Retirement Extreme. He’s applied systems thinking to lifestyle design, and it brilliantly covers all aspects of life. The most impactful idea I’ve taken from him is to design a “web of goals.” This concept helps you set up your life in a way where you have mutually-reinforcing positive goals and byproducts (maximizing synergy) while also reducing/eliminating negative byproducts (minimizing waste). The “web” focuses on the connections between your lifestyle choices and includes everything from health to wealth to wisdom. An example would be a web where you live within walking/biking distance of work and the grocery storeâyour commute doubles as your daily exercise (maximizing synergy) while eliminating the need for a car and saving money (minimizing waste).

đ§ Life Purpose (Sloww Stage 2)
The next two ideas are related to: Sloww Stage 2 (Life Purpose): How do I find a higher purpose?
5. Ikigai
Ikigai was a concept I discovered either during my existential crisis in 2015 or in 2016 when I was searching for purpose. But, my discovery of the viral 4-circle diagram led me down a path to uncover that it’s not really ikigai. Eventually, I put 5+ years of research and experimentation into an eBook: Ikigai 2.0: A Step-by-Step Guidebook to Finding Life Purpose & Making Money Meaningfully (+ Bonus Workbook). This is the process I used to find my own purpose, and it’s still the approach I recommend to everyone who asks me the best way to find purpose. In my mind, you will not find anything more comprehensive (yet concise) than Ikigai 2.0.

6. Birth Lottery
This idea is literally something that I now think about daily and has positively altered my worldview and how I interact with others in the world. If I could put anything on a billboard, this may be it. And, the best part is that the lottery of birth requires no science or spirituality to understand. What is the lottery of birth? It’s a reminder that you did not choose or control: to exist, your nature, your nurture, the location you were born into, the time you were born into, and so much more. No one did! And all of those shape you and your life pathâjust like they shape every other human. It may be one of the most simple, yet most profound, realizations any human can have to lead to compassion for all.

đ§ Mental Mastery (Sloww Stage 3)
The next two ideas are related to: Sloww Stage 3 (Mental Mastery): How do I build a better mind?
7. Mind Immunity
Mental models seem to get a bad rap from a lot of people. It seems to be because many think learning about mental models doesn’t equate to applying them. That’s true. But, at the same time, no awareness of something is a guarantee that it will not be applied. So, I fully believe in being aware of all these concepts, learning about them effectively through tactics like spaced repetition and interleaving, and integrating and embodying them through consistent practice in your day-to-day life. To help with this, I launched Mini Mind.

âŻď¸ Spiritual Seeing (Sloww Stage 4)

9. Self-Inquiry
