Expand your social circle
Every morning, write a short text message to a different friend.
You can ask them how they are, share a meme, or share a cute video. This will make you happy and make the other person happy.
Every day at your workplace, stop by a different office and share some stories with your colleagues.
If you are the company owner, make changes to encourage more social gatherings.
Expand the space; add more tables with more chairs, or add board games that your employers can play.
At least once a week, go out for a coffee with your colleagues or friends.
Organize a community soccer game or anything you like to play in your neighborhood.
