Being written in a foreign language it can be more difficult for you to fully understand and answer the question. Hence, it is very important to get all the keywords in order to proceed with writing your answer. A literal translation would be "MONEY do NOT make HAPPINESS. Do you AGREE?" (where all the keywords have been capitalised).
The next step is to plan out your essay structure, thinking about what you want to write about in your introduction and how you can start adding your personal stance on this topic. You need to provide reasons behind your choice and, being a discursive essay, it is also important to provide an opposing argument and make your reader understand why you do not agree with it. Then, you can conclude the essay by restating your opinion.
Try to present your essay in a nice way by dividing your points into different paragraphs and avoid cramming everything together. If you have troubles writing the essay, try sticking to easier sentence structures and avoid complex lexicon to make it more readable. Be careful of "false friend" words, too!
