You're probably familiar with TED Talks and have a collection of your favourite ones on a variety of topics. I love TED Talks because even though the Internet can be a chaotic space where there's a lot going on, these talks act as a well, full of information, inspiration and innovative ideas for people from all walks of life. The good folks over at TED recently curated a playlist that's right up this relationships editor's alley. It's called " In the mood for love" and, as the title connotes, it's about love. Whether you're curious about the different kinds of love that exist in this world, or need tips (and inspiration) on how to be a better lover, or if you simply love love and need more love, this is the the ultimate playlist for you. Here are three videos from that playlist that I think everyone should listen to. I'm biased because they're some of my favourites, but I think you will enjoy them, too. Editor's note: #3 tops my list of all-time favourite TED Talks because it combines two of my favourite things: writing letters and, well, love. <3

3. Love letters to strangers Hannah Brencher's mother always wrote her letters. So when she felt herself bottom into depression after college, she did what felt natural — she wrote love letters and left them for strangers to find. The act has become a global initiative, The World Needs More Love Letters, which rushes handwritten letters to those in need of a boost.
