If you live around trees and leaves, your gutters will fill up pretty quickly. And, if you live in a house with a pitched roof, you will quickly learn about getting water in your basement. That's never a pleasant experience.
Having had this happen, I learned the importance of keeping your gutters cleaned out. Over the course of a spring, summer and fall, they become filled with leaves, pine needles and other gunk.
Now I try hard to be proactive. I get the ladder and the hose, climb up and get my hands dirty removing all the gunk.
Is this worth it? Definitely. And that's why I have it on my list of 69 Things I've Learned in my almost 69 years of life.
