I am a open source enthusiast. It may sound silly but if something is open source, I like it a little more. I have gained a lot by using open source tools: I've learned, I've become more productive and I've done things I'd never imagine if it weren't by such tools.
The right tool can make a huge difference: you'll work better and faster by learning a little bit more about the tools you use. I like to invest a little of my time to learn more about the tools that are important to me.
