once you have some experience under your belt, these are non-issues:

• deciding to “learn Linux” the hard way by starting with a specialized distro (Slackware, Gentoo, Alpine)
• switching to unstable or testing branches before you’re ready ’cause you want bleeding edge or “stable is too far behind”
• playing around with third-party repositories before understanding them (PPAs in Ubuntu, AUR in Arch)
• bypassing the package manager (especially installing with curl | sudo sh)
• changing apps for no other reason than “it hasn’t been updated for a year”
