A step by step approach to write a research proposal

Let's write a research proposal. We will need to:
Hence, this tutorial will consist of six sections. In this tutorial, we will consider the following question as a "prototype" to go through all the six steps I described above. Once you familiarise yourself with these steps, you can develop your own research questions and see how these different steps will fit with your own question (we will leave this as an exercise for you to conduct after reading this manual). Here is the research question we will investigate here:
What is the relationship between happiness and heart disease? Are happier people less likely to die from heart disease? 
There is no real reason why this particular question was selected for this exercise.  You can argue that this topic has already been explored in the past, but here we can review the relevant literature and see if we can devise a study that can address some aspect of the knowledge base that has not been touched.
