Need to be reminded how good you are at your job? Keep a folder entitled "Awesome Emails."

"The majority of the emails in the folder are not revenue milestones or awards, but emails from my team and our customers who have shared how their lives changed for the better because of our work. I make it a habit to read a few of these every day, because they serve as an important reminder that how I lead affects people. Every day is an opportunity to make an impact." 

--Kyle Porter, CEO of SalesLoft, a sales engagement platform with more than 22,000 users, ranked for the second year as a "Fastest Growing Company" by Deloitte
