Our home — planet Earth. Approximately 8,000 miles wide, pole to pole. A little over 7.5 billion people wandering its surface.
Every person you’ve ever met, every laugh you’ve shared, every tear you’ve shed, took place here. On this rock, hurling through space and time.
The scale of our universe is incomprehensible…
Today, I will be showing you the easiest way to set up a public vanilla Minecraft server for you and your friends, without spending a single dollar. Without further ado, let’s begin!
In whatever directory you choose, create a new folder — this is where all of the server files will be downloaded and run from.

“Research your potential employer.”
“Don’t forget to thank your interviewers for their time.”
While these are all great tips to give you a slight advantage over other candidates, what really makes you stand out during an interview is actually purely subconscious:
