I love books! I also write them. FYI: I use this space for recs of books I wholeheartedly love only. My recs are honest, but I have social relationships with some of the romance authors whose books I rec.
This book is changing my life as we speak. I'm not a system administrator but I think the advice is great for anyone who does self-directed work (for me, writing). It's very straightforward, practical advice. I highly, highly recommend it.
