Get Touchy

When it comes to the other people you live with (like your spouse, your boo, your kids — hey, even your pets!), Rubin recommends getting as touchy-feely as possible. "Since starting The Happiness Project, I've become more committed to kissing and hugging my husband daily and being more affectionate with my kids — hugging them, giving them back rubs, anything. It's not a surprise, but people who are openly affectionate tend to have closer relationships, so even if you're not always able to spend quality time together, those physical connections can lead to an overall feeling of belonging." Meaning: major props for snuggle time.
