You are probably stressed at work, and miss flow http://en.wikipedia.org/wiki/Flow_(psychology) or what programmers call "not being in the zone".

Find a significant chunk of time, like a free Saturday. Make sure it's quiet and you cannot be disturbed. Set a manageable toy goal - easy enough that you can do it, but let it be a bit challanging to keep things interesting. Build it! That should give you a nice push forward.

PS. You could also find interesting questions on StackOverflow - many times they offer a bit of challenge, and you can cherry-pick issues in your comfort zone, also helps you practice writing.

Also, have a break from work! Cut the stress.
