I started using linux in 2011, but went full linux nerd in 2014/2015, while still in high school. Changed distros, changed OSs, changed everything, but full time it was linux all along, from ubuntu, to elementary os, to arch, to hackintosh, to solus, to endeavouros, to a lot of distros, but now i'm stable at cachyos (the optimized packages are amazing, ngl).
