• Learning new things
  • Certification
  • Sog, on twitter, 
  • Dive in and drink from the firehose and leverage the hyper-focusing ADHD ability to further accelerate learning. I learned Powershell, Go, and Rust in the last year-ish, in addition to a lot of pentesting-specific stuff. If you want it bad enough, you'll get it done.
  • The Mentor
  •  the way I learn new technology is by setting it up in my homelab messing around with it and messing  it up and building it up so many times until I fully get it 
  • Name_pending197
  • This is the way. I do the same, build it, document it, break it, repeat. I also find that learning and then presenting new technology to the rest of the team is an excellent way to retain knowledge. Explaining and demonstrating something to others is one of the best ways to understand it yourself. Especially if you know you will be questioned on it

Welcome to Episode 119 Main Topic

• Staying Healthy while working at a desk
• Obvious things
• “Office work”
• Generally means you are indoors
• You are not performing physically intense tasks
• You naturally burn less calories in a day
• You are sheltered from the sun
• It’s a lot easier to snack
• And this is even worse if you are a WFH worker
• And a lot easier to make poor dietary decisions
• This can be improved by WFH, if you can be disciplined 
• Not so obvious things
• Sitting all of the time is just plain bad for you
• But standing all the time is also not so great
• Mental impact
• In office
• Remote/WFH
• So what do we do about all of this?
• “Water cooler” meetings.
• Don't forget to move
• Limit your snacking
• Drink more water. You’re not drinking enough. Really, you’re not.
• Make sure to take mental breaks
• Take a dang lunch break
• in fact. eat regularly in general breakfast lunch dinner
• Either get to the gym or go for walks/runs/cycling/whatever you're into
• convertible desk
• treadmill desk?

• I absolutely did not spend that much though, maybe look for a lower cost alternative, the desk is not worth that price IMHO
