In just 135 characters, Minecraft creator Markuss Persson has expressed his feelings of existential meltdown on Twitter Saturday:

"The problem with getting everything is you run out of reasons to keep trying, and human interaction becomes impossible due to imbalance."

Twitter freakouts are normal, but this one goes a bit beyond the scale. Persson and Mojang AB sold Minecraft to Microsoft for $2.5 billion in 2014. Forbes reported that his personal net worth is about $1.3 billion.

You might be asking what a billionaire's life would be. Yes, the deal made him financially successful, bit it doesn't seem to reflect on other aspects of his life. This is obvious with some of his Tweets, which are filled with existential questions and various torments about his current life after Minecraft.

"Human interaction becomes impossible," and "I've never felt more isolated." Are just some of his Tweets. If you have a $70-million mansion in Beverly Hills with M&M towers, a movie theatre, 15 bathrooms, vodka and tequila bars, and toilets that cost $5,600 each, it would really be easy to feel alone.

Persson's case is a reminder that happiness is more than just being rich, beautiful, talented, or in love. Happiness can be understood in a scientific light. Serotonin, dopamine, and oxytocin running around the brain make a person happy.

Without enough supply of these hormones, happiness is something difficult to achieve. These hormones bring "pleasant sensations" to the body, which accounts for happiness.

Here is an example of his tweet last Saturday, "Hanging out in Ibiza with a bunch of friends and partying with famous people, able to do whatever I want, and I've never felt more isolated."

When it comes to his love life, he said, "Found a great girl, but she's afraid of me and my lifestyle and went with a normal person instead."
