This just makes me sad. Well, I suppose since the person writing it says she'd make the same choices all over again this is something she's okay with, but I can't imagine that this is something I'd be willing to do.
Nor can I imagine encouraging anyone to pursue a life like this.
In fact, I think if success in a field depends on living a life like this, someone needs to stir up that field a bit.
Once again, I feel incredibly lucky to have the job I do.
