The best piece of ..... someone gave me when the computer doesn't work was to turn the computer off, have a cup of coffee and then turn it on again

In many languages, such as German and Russian, the equivalent noun to ‘advice’ is countable, which makes it difficult for English learners to get used to the fact that ‘advice’ is not countable in English, so you will never hear someone say ‘please give me some advice’ or ‘give me some advises’. It’s always ‘a piece of advice’ or ‘a piece of information’.
