TECHNOLOGY OF WEEK: How Can I Overcome a Work Slump?

Dear Lifehacker,

I’ve been feeling discouraged at my job lately. My work isn’t as good as it used to be, my boss is on my case, and I just can’t seem to get excited about anything I’m doing. I love my job and want to stick with it. Have any suggestions for how I can get my energy and inspiration back to where it used to be?
