My Struggles with Learning Data Science

It took me a long time to learn data science. I made a lot of mistakes as I fumbled through learning R. I specifically had a tough time navigating the ever increasing landscape of tools and packages, trying to pick between R and Python, and getting lost along the way.

If you feel like this, you’re not alone. Coding is tough, data science is tough, and connecting it all with the business is tough.

If you feel like this, you’re not alone.

The good news is that, after years of learning, I was able to become a highly-rated business consultant working with Fortune 500 clients and my career advanced rapidly. More than that, I was able to help others in the community by developing open source software that has been downloaded over 1,000,000 times, and I found a real passion for coding.

In fact, that’s the driving reason that I created Business Science to help people like you and me that are struggling to learn data science for business (You can read about my personal journey here).

What I found out is that:

  1. Data Science does not have to be difficult, it just has to be taught smartly

  2. Anyone can learn data science fast provided they are motivated.
