About Author
Zack Hargrove
It’s me who writes exclusively incredibly awesome (it’s for me to decide) posts you can find online and particularly on this website. I’m a freelance writer and blogger, and I always find new effective ways of working faster and better. Also I am featured as a top columnist on Quora and author on Today.com and Elephant Journal.
