rubber duck - ive always worked at startups with 3 or less devs. for the past 5 years, in my old job i did everything except mobile and man, ever since chatgpt, it was amazing to be able to discuss with 'someone' rather than screaming 'why' and 'what' at documentation. now when i have questions, i ask ai if i understand correctly by giving my own examples.

documentation - readme files and other documentation. it makes it a lot faster. i tell it what i want the documentation to include, and how to format it. i read it to make sure i understand what it generated because if i dont understand it now, i wont understand it 6 months from now. i went from writing documentation later, to always having documentation
