this point is the main key of all successes (for me), and especially in Data science when you must have a multi-skills. so look for a new book, Tutos, courses.
Also create a new sphere around you that you will name it Data science friends, this community will helps you to keep you knowledge updated, and at the end read a lot (data science blogs, …).
Don’t Give Up
the start is always the must hard part of learning path, it’s not easy to have a good level in all data science sub-fields, for that you should to keep your stamina till that you have a good level in data science.
Be sure all your efforts will be paid after 🙂
Hope that Helps you 🙂
