Patience. It's hard to see the line or word you want to jump to and have to look at your keyboard and be like "what do I do?" For me it was basically tell myself "it's ok to be slow" and I started memorizing the navigation patterns from the top down of the `hx --tutor`. The further down you get on having that tutor file in muscle memory the easier it gets to want to ditch the mouse.
I switched from PyCharm and Sublime Text, although I admit I still use them from time to time when trying to grasp an entire codebase. Helix is my primary editor now and I wish I had the helix navigation and editing everywhere now lol.
Using vim motion extensions for my primary editors (VS Code & Visual Studio) for ~11 months at my day job while using vanilla neovim (no plugins, syntax highlighting, lsp) for the first 6 months on personal projects.
