Dog trainer Jerri Scherff kept seeing a man in her neighborhood walking with a dog leash in his hand, but without a dog. After driving by multiple times, she decided to pull over and ask him why.

On Instagram, she shared a tearful video about their heartwarming exchange and grieving their dogs.

“Finally this morning I said, ‘Can I ask you something?’ He said, ‘Yeah.’ ‘Did you lose your dog?'” Scherff says to the camera. She adds that he nodded to her, and she tearfully replied, “‘Me too.’ And then I just hugged him.”

Do you know someone who seems to have zero photography skills? Who somehow manages to make everyone look their worst whenever they’re behind the camera? The kind of person who can’t even frame a decent selfie?

If so, Iceland might have a job for them. And a decently paying one at that. 

Recently, Iceland Air made a post specifically seeking out “really bad photographers.” Virtually the only prerequisite was having  “no photography skills.” Those who knew terms like “composition, white balance, or color theory” need not apply.

There are simple things we know to be true about happiness: Going for a walk in the sunshine just feels good. So does a hug, or hearing your favorite song. Petting a dog puts most of us in a better mood. And so does a little bit of intense exercise. Maybe not during, but definitely after, when we’re basking in the afterglow of our effort.

The science behind life’s simple pleasures is where things start to get really interesting. Happiness isn’t just one feeling, it’s a collection of several different feelings, and many of them come from our brain’s internal pharmacy of “feel good” chemicals, or neurochemicals. They’re known as the four happy hormones: Oxytocin, serotonin, dopamine, and endorphins.

The big questions of existence like finding our purpose, doing work that matters, and finding love aside, it’s really the little things that send our brain happiness signals throughout the day. And these feelings are really easy to trigger intentionally, once you know how.

You know that feeling toward the end of a great vacation when you stop and think: I wish I could stay here forever. It might be an all-inclusive resort, a secluded beach, or a fun-filled cruise on the high seas that you just don’t want to leave. Of course, for most people, it’s a fantasy. You can’t just quit your job and live a permanent vacation. But what if you could?

Giving it all up and retiring to live on a cruise ship at 32 seems like a lifestyle choice only available to the ultra-wealthy. However, two financially savvy retired school teachers from Tennessee have managed to do just that, spending under $10,000 for the first eight months at sea.
