I feel your pain. The one that I really got into just recently was a reading list. I am always getting suggestions of a book to read and I want to capture that information quick, but I always do it in random places and in random formats. So I created a shortcut that asks for the “Title,” “Author,” and “Any Notes” (who recommended, why, etc.). Then that saves it to a Todoist task and creates an Evernote note. It wasn’t necessarily about making it quicker, but about doing it consistently after recognizing I organized things the same way (or at least I wanted to).
The other suggestion I always see is try to create something you already know, like a faux twitter client or a task manager, but that’s like real programming and not automation lol.
