What are you working on?
If someone asks you that, are you excited to tell them the answer?
I hope so. If not, you're wasting away.
No matter what your job is, no matter where you work, there's a way to create a project (on your own, on weekends if necessary), where the excitement is palpable, where something that might make a difference is right around the corner.
Hurry, go do that.
