What? Who the hell thinks this is healthy? This person is literally filling all their waking life with work. Even if you love the shit out of your job, you're neglecting your mental and physical health by working that long. (And in all likelihood, she doesn't love the shit out her job. You'll be pressed to find just one person on Earth who'd be happy spending every hour of their day "branding". And I'm a marketing manager!)
And it's not like this person doesn't have other options. She makes enough money to live in a fancy San Francisco apartment and hire on-demand services to do everything. So she's making bank. But all that money's just going to keep up an expensive lifestyle that she doesn't even have time to enjoy.
I just hope she's got a plan. Maybe save as much as possible and retire early. Otherwise, what is she doing with her life?
