How do you study and write a book in the meantime?

Answer 1

Writing while doing anything else is a matter of time management. You need to decide honestly how much time you need to spend on the "important" things - that is, the thing that is either giving you your paycheck or giving you your education - and make sure that you spend enough time working on that first. Then, decide how much time you want to spend writing - remember that it is just as much work writing as it is studying or doing any other job! - and set aside that much time every day. Most writers set a goal of a certain number of pages or words that they will write every day. Remember to leave time for enjoyable things like hobbies and socialization!
