As stated above, do what works best for you.
I don’t create LingQs, as for me it takes too much time, and in general I prefer to learn words in context, not from a dictionary definition. Thus I harvest example phrases such as Tout ira comme sur des roulettes. If I don’t understand a word, I check the sentence translation.
I allow the system to gradually automatically mark words as known. It’s only a very rough estimate, but provides some feedback.
