Our tendency to believe we know more than we do best illustrates

I don't really understand what your question is, but our tendency to believe we know the future and ours surroundings more than we do is a common thing. People think they know what can come and have a prediction, but there is always that sense of unknown that has to be factored in. Sometimes that portion that is unknown can be forgotten making it a surprise when something does not go our way. 

Everyone’s hair grows differently.

This question is an opinionated one, and we don’t know anything about the module or anything, thus we can not answer it. but if you are having trouble on what it is asking basically it is just asking to (using your knowledge on the topic) say which topics you were most interested and which were the most challenging.hope this : p
