I get a *lot* of e-mails and YouTube messages asking me how to become a system administrator. Usually I just point people at the blog or YouTube channel, but yesterday I decided to write up something a bit more complete. Here’s a slightly modified version for easy reading.
Asking Questions, doing Research, and getting Help
This is worth its virtual weight in gold: http://www.catb.org/esr/faqs/smart-questions.html
Subreddits are great. Check out /r/linux, /r/sysadmin, /r/networking, /r/programming, and others. Long story short, find communities that are doing things you’re interested in.
No one will sign up to mentor you, but if you show interest and effort, work on practical projects, and ask well-prepared questions, people will generally treat you well and help you out.
