Every day, I go to work, and I am beset by several shelves full of computers whose owners have been waiting too long to get them back. I select four or five of the most urgent machines and get started (leaving the remaining 15 or so for another day) and I push hard to make progress on their repair. All the while, I frequently put my screwdriver down to answer phones and assist customers at the counter. In fact, in a given day, I may spend three quarters of my paid time at the counter, receiving new computers, talking with angry customers, and doing damage control for unexpected issues.
Every day, I expose myself to near constant negativity. And I love my job. I love it because it keeps me here in an existence that I love.
