The major mistake that most of the students or learners do is to venture into a career without having enough knowledge on the profession on this end up messing them up when they find out that it is not what they really wanted. It is therefore advised that you do enough research about the career you want to venture into in order to know the ins-and-outs. For this reason, I am going to help you by giving you the things you need to know before venturing into a data Science career. Find out more at www.dataquest.io.
To start with, you need first to understand the different roles found in data Science and pick the right one which you are comfortable with and one which you will enjoy. There are roles such as machine learning expert, data engineering, data scientist, a data visualization expert and more others. When you start a particular course in Data Science, you need to make sure that you do it to the final and that's why you are supposed to be sure of what you are choosing. The other thing you need to do is to select a language or a tool and make sure you stick to it. Even though there are several languages and tools in Data Science, you need to know that the tools are just a way of implementation, but having an understanding of the concept is quite essential. You can view here for more information.
The other thing to do will be to find a group of people or other learners and most importantly, who are dealing with the same tool or language as you so that you get motivated by them. This is because it also eases your studies because of the fact that you will get to learn from your peers where you did not understand and also you will have a group of people who will be trying new things with you. It is always good to invent or come up with something using the knowledge that you have learnt in class with your friends and so doing projects with your peers will be really recommended. You are also highly advised that you should not only dwell on the theory part of data Science but is well on the practical part since it helps in explaining further about the theory you have learnt and how whatever you have learnt can be applied in reality.
