Take time at the beginning of your research to think about your data needs and how you will manage them. Think about all the expected stages of your own research project as well as how the data may live on afterwards.
While a formal Data Management Plan is not always necessary it will save you time to think about the entire lifecycle of your data and write down how you will take care of your data throughout all it's stages.
