A lot of people feel this way, especially when they are developing on legacy systems or doing standard line of business apps.
I would suggest finding an open source project you are passionate about. There are some really cool open source software applications popping up that need passionate developers like you to get involved.
That's how you make an impact - get involved and do something that benefits the community, and that you can be proud to have put your name on!
It might not help so much with your day job, but it will certainly open up new opportunities for you, improve your skills and look great on your CV. Plus it's a lot of fun!
Do a search in GitHub, or if you program in C# come take a look at what we're doing (yes, you can change the world!): https://github.com/Warewolf-ESB/Warewolf-ESB
