With the age of social media, everyone is posting pictures to Instamatic, Facebook, twitter, and tumblr. They show food, vacations, their pets, their favorite celebrities, their crushes, their achievements, and so on and so forth.
Since we are constantly updating our friends of where we're going in a month or what is happening at the end of the year, jealousy and envy can rear its ugly head and it comes from comparison. Comparison is the root of all evils and let me explain why: you're comparing your life to people's high points.
Let me dive into that a bit further: 20-something people post photos of going to parties be it game nights or alcohol based. They are showing these extravagant vacations with friends, family, or with their boyfriend or girlfriend. They are overall showing fun and amazing moments in their lives while you are sitting on the computer browsing it.
But that's the point. They are only showing you the good parts of their lives. You don't know if someone has a really bad fight with their boyfriend or girlfriend. You don't know if someone is having familial problems. You don't know if someone is having various personal problems.
Comparing your life to someone based on their internet persona will only lead to the demise of your joy. As real as you may be online, unless you give hints to how you're feeling at a certain point in time, everyone has an internet persona.
If you want to be happier, don' compare your like to one photo, just focus on the good things in your life at the moment. Sure, a friend may be taking a trip to Australia you have may have dreamt of going on, but you may be having the same great time enjoying relaxing at home with a friend.
