The first thing is to chose a topic or a research area that you like. Try to read literature on the chosen area to make sure that enough materials are available. Also, try to develop a positive relationship with your supervisor. Furthermore, plan your research activities. Determination to succeed is also very important.

I agree with Bahtilla Marinette's opinion.

In addition I write my opinion.

There are two divisions of doctoral dissertation.

1: Literature research Here are the hypotheses and models. Category

2: Survey and verification research. Prove a hypothesis or model. At that time, case analysis and statistical data analysis are effective.

I think that these two are necessary.

How about ??

Work hard and effectively in close cooperation with your adviser until you discover your own tips.

Look into the 7 habits of highly effective people (Steven Covey). What is important is to classify the tasks that you will have to perform and to batch these tasks in relation to the task type. For instance bundeling research or analysis efforts in one period and or bundeling writing tasks in another period will allow you to find what productive people refer to as Flow or a flow state. This Flow allows you to focus and also allows you to pick up the activities that you are doing at that point in time easier, then when you are performing different activities or taks types simultaneously and or tasks that are not bundled. This also refers to the story included in the book Ghost in the machine (Arthur Koestler):

"There were once two Swiss watchmakers named Bios and Mekhos, who made very fine and expensive watches. Their names may sound a little strange, but their fathers had a smattering of Greek and were fond of riddles. Although their watches were in equal demand, Bios prospered, while Mekhos just struggled along; in the end he had to close his shop and take a job as a mechanic with Bios. The people in the town argued for a long time over the reasons for this development and each had a different theory to offer, until the true explanation leaked out and proved to be both simple and surprising. The watches they made consisted of about one thousand parts each, but the two rivals had used different methods to put them together. Mekhos had assembled his watches bit by bit — rather like making a mosaic floor out of small coloured stones. Thus each time when he was disturbed in his work and had to put down a partly assembled watch, it fell to pieces and he had to start again from scratch. Bios, on the other hand, had designed a method of making watches by constructing, for a start, sub-assemblies of about ten components, each of which held together as an independent unit. Ten of these sub-assemblies could then be fitted together into a sub-system of a higher order; and ten of these sub-systems constituted the whole watch. This method proved to have two immense advantages. In the first place, each time there was an interruption or a disturbance, and Bios had to put down, or even drop, the watch he was working on, it did not decompose into its elementary bits; instead of starting all over again, he merely had to reassemble that particular sub-assembly on which he was working at the time; so that at worst (if the disturbance came when he had nearly finished the sub-assembly in hand) he had to repeat nine assembling operations, and at best none at all. Now it is easy to show mathematically that if a watch consists of a thousand bits, and if some disturbance occurs at an average of once in every hundred assembling operations — then Mekhos will take four thousand times longer to assemble a watch than Bios. Instead of a single day, it will take him eleven years. And if for mechanical bits, we substitute amino acids, protein molecules, organelles, and so on, the ratio between the time-scales becomes astronomical; some calculations indicate that the whole lifetime of the earth would be insufficient for producing even an amoeba — unless he becomes converted to Bios’ method and proceeds hierarchically, from simple sub-assemblies to more complex ones.

A second advantage of Bios’ method is of course that the finished product will, be incomparably more resistant to damage, and much easier to maintain, regulate and repair, than Mekhos’ unstable mosaic of atomic bits. We do not know what forms of life have evolved on other planets in the universe, but we can safely assume that wherever there is life , it must he hierarchically organized. "

Hence, think first, assess the elements: know-how, know-what, know-why, design a structure, bundle, create modules and perform the tasks in sequence and in a modular approach.
