What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content,

just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of"

nested selector

system.

How to flip the script on your fears:

Where am I allowing my fear to distort my reality?

The stoic philosopher Seneca famously wrote, "We suffer more in imagination than in reality."

There is something in your life that you are avoiding because fear is distorting your reality.

It can strike in any area of life:

  • The fear that you won't be able to find another job if you quit this one.
  • The fear that you won't be able to find another partner if you leave this one.
  • The fear that you won't be able to find another friend if you cut off this one.
  • The fear that you aren't productive if you don't keep yourself busy all the time.
  • The fear that you won't be loved if you don't act as you're supposed to act.

The fear causes you to overstate the negatives and ignore the positives altogether.

Flip the script on your fears:

  • What if I find a better job after quitting this one?
  • What if I find a more loving, supportive partner after leaving this one?
  • What if I find a more loyal, trusting friend after cutting this one?
  • What if I am more productive by allowing myself to be less busy?
  • What if I am more loved for being myself?

Stop allowing fear to distort your reality. Embrace the discomfort and see the other side.

The power of patience in an impatient world:

"A man who is a master of patience is master of everything else." - George Savile

If you can be still while others rush to move.

If you can delay gratification while others rush to feel it.

If you can make time your friend, not your enemy.

You will win.

How I finally kicked my afternoon slump:

The 80% Rule

I'm an early riser, but I've always struggled with a rough afternoon slump.

I'd feel energized and focused all morning—knock out a workout, focus work, and time with my wife and son—but inevitably, after lunch, I felt drained.

The window from 1-3pm was like a dead-zone in my day: Tired, unfocused, and grazing lazily across low-value tasks.

But I finally found a system that works to kick the afternoon slump: The 80% Rule.

The Okinawans of Japan were made famous by Dan Buettner's Blue Zones research for their incredible longevity. One of the principles of that longevity was an ancient Japanese principle called Hara hachi bun me, which translates to "Eat until you are eight parts full."

Eating causes the body to move blood and energy towards the digestive system. By eating a big lunch while sitting down at my desk (a staple of my old routine), I was basically triggering my body to go into digestive recovery mode.

This explained my terrible afternoon slump.

My new afternoon system that worked wonders in my life:

  • Lighter lunch focused on protein, veggies, and fats (light on carbohydrates, which make me sleepy).
  • 15-30 minute walk right after eating to promote digestion and mental clarity.
  • At least 16 ounces of water after the walk.
  • Lightly caffeinated beverage (green tea) if in need of a boost.

Following the 80% Rule at lunch helped me completely change my afternoon productivity. Rather than forcing myself to grind through the drowsiness, I feel more alert and able to take on important tasks that create real progress.

If you ever struggle with the afternoon slump, give this system a shot. You won't regret it.

Interesting study on sleep irregularity:

Great post on an important new study on the benefits of sleep regularity (going to sleep and waking up at the same/similar time each day).

P.S. If you haven't already read it, Dr. Matthew Walker's book is terrific.

Concept to live by for greater happiness:

The Norwegian secret: how friluftsliv boosts health and happiness

This is a great read on the Norwegian concept of friluftsliv (literal translation: free air life), which is the regular focus on time in nature as the key to health, fulfillment, and happiness.

According to a survey cited in the article, 77% of Norwegians spend time in nature on a weekly basis.

Anecdotally, I feel much happier on days when I spend considerable time outside, so I'm buying it...

I'm all in on that friluftsliv life!
