I’ve got my copy of Time Management for System Administrators that I pre-ordered 2 weeks ago last weekend, and I’ve also bought Brain Performance Hacks book a week ago. After few days and went through over half of the 2 books, I feel like accomplishing more things within the same time space than before 
Though it might not physically be true as I dont make any measurements, but hey, it did make me feel better that I blog about it 
The content of the 2 books sometimes doesn’t agree with each other, but to have read and probably understand both books, we can choose what’s the best for us. They are both great and my rating for them would be "Highly Recommended".
