We’re more likely to be happier if we’re in direct contact with someone who’s constantly happy themselves. Their mood tends to be contagious in everything they do since their emotions are strong. An example of this is could be seen in a teacher who’s really excited about their profession.Their students will be interested in what they have to say and feel happy and excited about the subject. Maybe a moment of happiness is just enjoying a sunset at the end of the day too. If you’re feeling down, meet up with a couple of friends — they’ll “contaminate” you.
