Fzf all you can, not just inside vim, but also use it to switch between tmux sessions in an instant. I have a tmux manager on top of tmuxp that is able to start / switch to already started sessions via fzf.

Identify patterns you use a lot and make snippets out of them. Create project templates.

Have a folder where you dump reference / things that need to be really easy to find, and set up vim to search into that instantly, no matter where you are.

Keep an inbox file to throw things in, make a wm bind a script to prompt for text and append it there via zenity. Don't throw links into it, it's gonna be a bookmark dump.

Make sure your todo system is a keybind away at all times.

Review your way of working, challenge, and improve it. Be lazy, but only when you afford it.
