Welcome aboard! Great starting point with Python and the M5Stick/Flipper - hands-on tools make learning fun. For cybersecurity, focus on networking basics (try CompTIA Network+), then dive into Linux, bash, and tools like Wireshark or Nmap. Use your old computer for practice: install Kali Linux and start with safe, local labs like TryHackMe or Hack The Box. Keep learning, stay curious, and always practice ethically. You’re on the right path - just take it one step at a time!
