Hey Reader,

A career change is not a side project.

I know because I've done it twice. Project Manager to nurse. Nurse to DevOps Engineer.

Both times I underestimated what it would do to me.

Not the technical part, that is usually fine. I'm talking about the the psychological part.

There's a reason for that, and it's been scientifically measured since 1967.

Two psychiatrists at the University of Washington — Thomas Holmes and Richard Rahe — spent years studying the medical records of over 5,000 patients.

They wanted to understand why some people got sick after major life changes and others didn't.

What they built was the Social Readjustment Rating Scale. ​

They took 43 life events and gave each one a stress score based on how much mental readjustment it demanded, regardless of whether the event was positive or negative.

Here's how they measured it. They gave 394 people the list of events and told them that "marriage" was worth 500 points. Then they asked: compared to getting married, how much readjustment does each of these other events require? More? Less? How much?

They averaged the results and divided by 10. Marriage became 50 Life Change Units. Everything else scaled from there.

Death of a spouse: 100. Divorce: 73. Getting fired: 47.

"Change to a different line of work" scored 36. That puts a career change in the top half of all 43 life events — higher than trouble with in-laws, higher than outstanding personal achievement, higher than starting or finishing school.

But that single number understates the real impact.

Career changes never happen alone.

When you switch careers, you also get financial uncertainty (38 points), changed work hours (20 points), disrupted sleep (16 points), and a shifted social life (18 points). Some of you will relocate (20 points) or take on a new mortgage (32 points).

Stack those together and you're at 160+ Life Change Units from one career decision.

Holmes and Rahe found that anyone scoring above 150 in a 12-month period has a 50% chance of a major health breakdown within two years. Above 300, that jumps to 80%.

This wasn't theoretical. In 1970, Rahe tested the scale on 2,664 U.S. Navy sailors before they deployed for 6-8 months.

The sailors who had the highest life change scores before deployment got sick at 1.6x the rate of those with the lowest scores.

The scale predicted illness before it happened.

The research has been validated multiple times since — most recently in 2023, when a PLOS ONE study of 540 adults confirmed the original findings still hold after 56 years of societal change.

I didn't know any of this when I left nursing. I just knew I couldn't focus.

I wasn't sleeping. I questioned the decision every single day for months.

Years later, looking back, three things got me through it.

First: sleep. Not "try to sleep more." Treating 7-8 hours like a non-negotiable appointment. Your brain is rebuilding its identity during a career change. It cannot do that on 5 hours.

Second: meditation. 20 minutes, right after waking up. Focus on your breath at the nose tip. It resets your mental baseline. When your entire professional identity is in flux, you need one thing that stays fixed. Your breath is that thing.

Third: a guide. Someone who has already walked the exact path you're on. The moments I almost quit were the moments I had nobody to ask. Nobody who had done it. Nobody who could say "that's normal, keep going, here's what comes next."

That's exactly why KubeCraft exists. 800+ engineers making the same career change you are. A structured system.

And me — someone who went from zero tech experience to Microsoft MVP — available when you get stuck. I mentor you directly on the several coaching calls we host every single week.

A career change scores higher on the stress scale than most people realize. Don't do it without a support system.

To keep the quality high, we're only allowing in 10 new students in April.
