If you are like me who is starting career in Data Science field, there's no other good advice from people who are notable in the same field; of course, experience and proper education are advisable.
I am currently reading a Book of compilations of insights from Data Scientists across the board - from Marketing, Astrophysics, Entrepreneurship, Information Technology, Classical Statistics and Machine Learning, etc. This is my first non-fictional book I picked up apart from the R Programming book that came along with the R Programming Class co-offered by Johns Hopkins University and Coursera as part of the Data Science Specialization.
The book is free or you can pay a considerate amount if you want.
