Needs arise from a combination of factors. It’s worth thinking about these factors, bearing in mind that needs may be either concrete, such as writing an essay, or more psychological e.g. overcoming inhibition.
What languages and what specific language skills and purposes are important for you at university? And how about later on in life? Does motivation affect your needs, or perhaps vice-versa? If so, in what way? Is there anything that you think could be useful but that you have been avoiding? Do you rarely stray from your comfort zone? At times our needs are not too clear: self-reflection on our learning process may help us specify and prioritise them.
