I got a new job as a Linux sysadmin (my first one)

Hello,

For the past month, I have undergone a hiring process and right now, I have just signed a contract starting from June 1st stating that I'm gonna have a new job becoming a Linux sysadmin working with mostly Debian OS based servers and infrastructure. Throw in some Zabbix monitoring, containers, server backups and management etc into the mix and that's it. Zero end-user support. This is my first job in Linux and my first job in sysadmin as well. I am happy because after 6 years of being in IT tech support (working mostly with Windows), I finally ditch it. Tech support just sucked the soul out of me so sysadmin is a breath of fresh air. The pay is also good IMO.

Do you have any advice for a newcomer into this field?
