Organizing your project and daily work

Suppose you are starting a new project, you just got the data and want to build a model.

Make your own assumptions about the deadline , workload etc.


How would you structure your day, the project timeline, prioritization?

I am recent graduate and did few internships and i feel like i lack basic planning and organizational skills to succeed in my job, how do you learn this , do this and where can i learn more ?

assumptions basic build daily data datascience etc graduate internships planning project timeline work
