A large factor in this situation is that I regularly jump between several different languages, but nevertheless, it is frustrating to have to pause my flow and look up things so regularly.
Perhaps it is a patience thing with my older age, but I find nowadays the biggest thing putting me off starting new projects is just all the sheer mundaneness of setting up repositories and working folders, getting third party assets together, configuring project management tools etc.
You would think that familiarity and practice would make these sorts of things automatic and fluid over time, but the opposite seems to be true.
