Things I Have Learned About Data Science - KDnuggets

If you think your data is clean, perhaps you have not looked into it yet; if you think your data is messy, it's even messier. Nobody cares how you did it; just do it correctly. People do not care how much you know until they know how much you care (about them and their business). In 2-3 years, nobody will talk about Big Data anymore. It always pays off to be damn good at numbers, Excel, and PowerPoint (and yes, presentation skills); Tableau is a big plus. Downloading some code and data and running them does not make you a data scientist. The same is true for doing data science courses. Participating in Kaggle competitions does not make you a data scientist, although it can help you learn from others. Winning Kaggle competitions does not necessarily make you a good data scientist. ETL is always needed - be good at it and learn a good tool for it (Talend is a good one). Also, learn scripting languages for ETL. Deep learning is cool, but it's still cool if you don't use it when you don't need it, and in 99% of cases you don't need it. Algorithms are commodities, your data is not. Ideas are commodities, execution is not. Deep learning expertise will soon become a commodity; problem-solving skills won't.
