sphair: I think you're talking about gumption, not inspiration. Inspiration is great for realizing the solution to a problem. Gumption is needed to actually implement that solution.

On that note, if i may be so bold to dispense some advice, i would recommend forgetting about it for a bit. When i find that i'm slacking off at work and avoiding my computer at home, i try to take a step back and relax. Then i find something that's completely unrelated to what i should be working on, and let myself get into it. It's good for releasing tension, and lets you be productive on something, which can help you go back to being productive on whatever you were supposed to be doing in the first place.

In fact, i end up doing alot of my fun stuff that way, as a decompressor before hitting the stuff people are expecting from me. Stream of the Web came into existence that way. Give it a shot.

And good luck. :)
