Same is the case with me. In work I don't get to code but my work involves around support. I love programming. Once I get back from home I always make sure I read tweets of smart people, read hackerne.ws, reddit, quora and mailing list.

As a result of this I get excited to find some thing interesting out of the above mentioned and start working on my own ideas.

Simple keep following and get updates about people whom consider smart and get to know what they are upto, this pushes you.
