In this vein, has anyone had organizational success hiring a high level PA? Not talking about the cheap offshore PA's from upwork, but a native English speaker with training and a higher rate. I find I have more projects than I can track. A good PA/project manager might help with that, but it's hard to know in advance or how to hire one. I run an online business, and have contractors for specific tasks, but I'm really the only one with a bird's eye view. And frankly, project management is my weak point.
