How does one stop being boring?

I've been thinking about that all day, how do you stop being boring? How can you throw some excitement back into your life on limited resources (Arizona) and limited funds (part time salary)? I've been sitting here wondering for the past couple days how my life became so narrow. To the point where the biggest news I could share in a good, long while was piercing my ears a few times.
It's depressing, I used to be so much more fun than this. I've become way too responsible, too cautious, too solitary, too dependant. I want to have fun again, I want to know how I can spice up my summer.
