I get a bit tired of the generalisations in OA. Sometimes there is far more wrong with life than just not taking good enough care of yourself in terms of sleep, diet and exercise. Sometimes you need professional help and (even if not) what is good for one person might not help you one bit.
My personal bugbear is mindfulness: tried it, didn't get on with it, do not see it as the holy grail of wellbeing -- as some people seem to claim it is. It works for them, that's fine. Doesn't mean it works for everyone.

> Claire, a 37-year-old in a highly competitive industry, was sent on a three-day mindfulness course with colleagues as part of a training programme. "Initially, I found it relaxing," she says, "but then I found I felt completely zoned out while doing it. Within two or three hours of later sessions, I was starting to really, really panic." The sessions resurfaced memories of her traumatic childhood, and she experienced a series of panic attacks. "Somehow, the course triggered things I had previously got over," Claire says. "I had a breakdown and spent three months in a psychiatric unit. It was a depressive breakdown with psychotic elements related to the trauma, and several dissociative episodes."
Of course, people will say she clearly had deeper issues but that's my point.
Seems like a small sample size. Luck helps some along more than others and it's spotty in its distribution.
She doesn't say if her friend is a business owner. She mentioned she wanted to start a business but she doesn't say if that was part of what she was working on.
Her friend doing 5 hours of coding in one day is a lot. It's probably more than a typical 9-5 office coder puts in. Especially working from home with relatively few distractions.
But when you own a business, once you have finished putting in your 5 hours of coding, you still have the rest of the business to take care of. One full time job is done, then you start the next one.
