But companies want me to be REALLY EXCITED like I could always get in my 20s. I just can't get that excited anymore; it takes too much extra energy that I'd rather conserve for doing real work that matters to me.
Thankfully, I found an amazing consulting firm constructed of around 15-20 folks with a similar history that really valued work-life balance and carefully chose its clients based on respecting those boundaries. We did really great work, within those boundaries. As a starting point for a search for that kind of company, I would recommend weworkremotely.com (where I found that firm), because they're generally companies willing to make convenience/control tradeoffs (such as working with remote employees) in order to get stuff done.
