I want to create a server for minecraft, is it worth it?

Def Takes dedication, and allot of time.
I've ran servers for years, and even bought a server mainframe for my office.
Just take your time and plan on everything (Design, Theme, layout etc.)
Then focus on what you want for your players (items, Crates, Rewards, Ranks, etc.)
Most important is the Commands System, Permissions System, Work on knowing
what commands and permission does what, and how it works.
then you should be good to go
