I watch experienced sysadmins move through the terminal effortlessly, remember obscure Linux internals, and use keyboard shortcuts without thinking. If you have reached that level, what helped you most besides simply accumulating years of experience? Did you build a homelab, run servers, deliberately avoid graphical tools, read documentation, or learn through troubleshooting real problems?

Don’t try to memorize every command in isolation. Start with a problem you actually want to solve, then learn the tools involved. Read the command’s help output and manual page, type the command yourself, and make sure you understand every option before running it. Useful commands such as `find`, `grep`, `awk`, `sed`, `ssh`, `rsync`, and the permission tools are worth learning deeply because they combine well through pipes and scripts.
Force yourself to use a command-line-only environment for a while. Run a Linux server in a virtual machine, manage it over SSH, and avoid installing a desktop unless you truly need one. Tab completion, reverse history search with Ctrl-R, the up arrow, and built-in help will become indispensable. You can still use a graphical interface when it is the better tool; the point is to build fluency, not to make things needlessly difficult.
The biggest factor is using the terminal for real tasks over and over. Build something useful, break it, troubleshoot it, and rebuild it. A homelab with a few virtual machines or containers is perfect because you can experiment without risking production systems. Over time, commands become muscle memory, and even forgotten commands are easy to rediscover because you understand the underlying concepts.
Daily immersion helps enormously. Use the CLI for ordinary tasks like navigating files, editing configuration, moving data, checking processes, and managing services. If you started with graphical tools, give yourself small challenges instead of trying to eliminate the GUI overnight. Eventually you stop memorizing isolated shortcuts and start recognizing patterns in shells, permissions, processes, filesystems, and pipelines.
A lot of the apparent wizardry is just knowing how to investigate. Experienced admins still look things up constantly. They know where to search, how to read logs, how to check versions, how to test safely, and how to create a rollback plan. Keep notes and document both the command that fixed something and how to undo it. Repeating that process with real projects is more valuable than passively reading documentation.

That makes sense. I tend to remember commands much better when they are attached to a problem I had to solve rather than when I study lists of syntax.
