Chrome: If you're the type who enjoys a little motivational push through the day in the form of an inspiring quote, New Tab Motivation for Chrome delivers, with a random quote each time you open a new tab. The extension itself is pretty simple. Every time you open a tab, you get a new quote by someone like the Dalai Lama, Lao Tzu, Dale Carnegie and Tony Robbins — obviously some quotes more interesting and thoughtful than others. You'll probably have to plug through some eyeroll-worthy ones to find something that will help you get motivated to push through the low points of the workday, but since you get a new quote with each tab, it's as simple as closing and opening another, or ignoring it until you have a reason to open a new one.
