Friday thought: Not every season is about pushing harder.
Some seasons are about maintenance, reflection, and preparing for what’s next.
If you’re ending the year tired, uncertain, or in transition — that’s okay.
Momentum doesn’t always look loud.

Winter slowdown is a great time for homelab projects:
• Snapshot everything before you touch it
• Document one thing you “just remember”
• Rebuild a service from scratch to see if it’s still worth running
• Kill at least one container or VM you don’t actually […]

Midweek question for #sysadmins and #it folks:
When things slow down a bit toward the end of the year, do you tend to:
• Clean up old configs and tech debt
• Experiment in your homelab
• Learn something new
• Or… just keep the lights on and coast?
No wrong […]

Friday Reflections:
Someone gave me great advice recently:

It’s simple, but it’s helped me wind down, rest deeper, and reset for the next day.
