Data science skills enhancement needs constant efforts and practices over months and months. Additionally, you should have the capacity for playing with data and mathematics. Not everyone can see the data in the same way and can obtain information from what is underlying. You can start off with a simple set of data with a lesser number of features. Try to plot graphs, and study this data may be in a simple tool like XL. There are many more sophisticated tools such as SAS, Python, Matlab, R and hundreds of them. And you should get only these tools once you start becoming friendly with data and data starts responding to your friend request.
