I took my first sabbatical at 25, with only a few years in the industry, making a lot less and I think $35k in the bank. Everyone told me I was crazy putting a gap in my CV, spending savings, etc. but I did anyway.

It was easily the best two years of my life, I travelled South America and Asia without a care in the world until the money was gone. Then I went back to work without an issue and have continued taking long periods off throughout my career. These days I'm a remote contractor, and even though I can and do work from anywhere I regularly still take months off at a time. I have a lot of savings too and a fully paid house in a country I love.

My point is that we create the anxiety for ourselves. A different lifestyle is possible if you make certain choices.

I find both management and devs are to blame. For some reason the amazingly knowledgeable developers I read on here daily are never to be found at work.
