It is essential that you keep on learning new things as it is essential for your personal growth and it would require you to properly manage your time. One example of this is that I personally set aside one hour per day so that I can read the new happenings in analytics. Additionally, I also make sure to learn one new business or technical fact per day. As a result of this, after 10 years, I would know 3,652 facts given that I continue to revise and go over what I have already learnt. Thankfully, there are endless materials on the Internet which you can learn from so it is essential that you make the time for learning every day until it becomes a routine. You should have a particular time that you usually read as well as sources that you can easily access. By creating a list of topics to read and learn about, it will help you to make the most of your time and it will essentially increase your overall knowledge of the analytics field.

My personal career in analytics started in the Financial Services. However, over time, I learned more about telecommunications, automotive and entertainment domains. This occurred because of cyclical growth of these sectors as they have different boom and low times. Basically, if in one particular sector there was a lot less growth and projects available, I would still be able to get projects in another sector or domain.
By having expertise in more than one business domain, it will help you to have more options. However, if you only have expertise in one domain then it will reduce your ability to grow in your analytics career and reduce your mobility within the industry.
To put this into perspective, I personally know many SAS experts who have a lot of difficulty learning R. Also, there are people who know the SPSS language and they are trying to learn the SAS language so they can get those type of jobs. There are also many R programmers who have found by learning C++ it has helped them immensely in their careers. Unfortunately, as you age, you will typically find it a lot more challenging to learn a new programming language, so you should strive to learn another language asap. When you increase your skill set, it will help you to become less dependent on one particular software or programmer. It will also ensure that you increase your own personal job prospects since you will be experienced and knowledgeable of multiple platforms.
When you have a great deal of expertise, it will give you greater credibility and will help you to make better decisions. Being a business analyst means that you are an advisor and you should strive to become published in various white papers, books, articles etc so that your expertise can become solidified. If you want to become a real expert, then you should keep learning in your specific area and never stop learning.
You should carefully choose you who follow and network with in person and online. You should use Stack, LinkedIn, Quora etc in order to network. This is essential for professionals and can help you to get assistance in your job as well as find new jobs or additional work.
