Help! I'm addicted to Pinterest!

I have been pinning and pinning all these awesome ideas I find on Pinterest...I think I'm addicted. Luckily, it motivates me to do that I normally wouldn't end up doing.
For example:
Our shower head was filthy! It's been filthy since we moved here in September.
So today, I was on Pinterest and saw a great idea.
Simply tie a little Baggie of vinegar around your shower head. Leave it there for a couple hours. In no time, it's spick and span! You don't even have to scrub!
Here's the website: http://www.areal-lifehousewife.com/2011/11/tip-4-how-to-clean-shower-head.html/
I've inserted pictures so you can see how well it turned out. I think it's a marvelous idea! Definitely worth it.
