If you want a faster and arguably more accurate way to do translation, you might think about using DeepL because it’s got a desktop application that allows you to translate something just by hitting Ctrl+C twice. DeepL is generally considered to be more accurate and to give more nuanced translations than Google Translate.
I don’t know if I’d consider what you’re experiencing a problem, per say, while it’s certainly a good idea to try translating yourself first, it’s not always feasible to do that on a long piece of text if you’ve not got the time.
