【推荐1】Have you ever heard of Big Data or are you familiar with Data Scientists and Data Engineers? They are probably new job titles, but the core job roles have been around for a while.

Data Analysts are experienced data professionals in their organization who can question and process data, provide reports, summarize and visualize data. They have a strong understanding of how to influence existing tools and methods to solve a problem.     2    . However, they are not expected to deal with analyzing big data, nor are they typically expected to have the mathematical or research background to develop new algorithms for specific problems.

They use all of these skills to meet the enterprise-wide self-service needs. BI Developers are typically not expected to perform data analyses.

Data Engineers are the data professionals who prepare the “big data” infrastructure to be analyzed by Data Scientists.     4    . Then, they write complex queries on that, make sure it is easily accessible, works smoothly, and their goal is optimizing（优化）the performance of their company’s big data ecosystem.

They might also run some ETL (Extract, Transform and Load) on top of big datasets and create big data warehouses that can be used for reporting or analysis by data scientists.

【推荐2】With so many investments required of us to succeed - time, resources, talents, responsibilities, even finances for our retirement - it’s easy to lose sight of the most difficult investment of all to commit to : ourselves.

Getting to the point where you’re ready to start upgrading to you 2.0 isn’t easy. But it doesn’t mean dropping the ball everywhere else. It’s not about omissions, but admissions. Come clean with yourself to kick-start your personal growth.

Unstuck starts with “u”

No one purposely chooses to stop learning and growing again, it just kind of happens in a lot of daily responsibilities and life. And if it were easy to just kick it into gear（ 档 位 ）again, you would have already done it. But the truth is inescapable. If you want to get off that place to higher ground, it’s up to you and only you. No one will just hand you a steady stream of opportunities for growth.

You’ve been working in your life, not on it

Activity is often confused with acceleration（忙碌）. I was guilty of this for years in working place - staying always busy but not admitting I was bored. I was lost in activity and not steeping back to take time to question what I wanted my life to be. Once I began working on my life - quitting corporate, becoming an entrepreneur, restructuring to my life - I started growing once again. And I’ve never been happier.

Things aren’t happening to you, they’re happening for you

A victim mentality（心态）is the enemy of personal growth. Lamenting over everything that has gone wrong in your life only wastes energy from working to make more things go right. If you want to kick-start growth, you must view setbacks as having a purpose, and then put them in their place. The past shouldn’t run or define you - only fuel you.

The perfect time to start doesn’t exist

I had so many things that had to be just right before I could make my long-planned leap from corporate. I’d tell myself, “I’d love to go for it right now, but practically speaking.” Well, guess what? Practicality is poison. It’s the convenient excuse stopping you from what you’re meant to become.

It’s time to unplug others’ opinions

Grow where you want to grow. Learn what you want to learn. Wherever you are on the scale of hat you want to learn next - be it beginner or near - expert own it, be proud of it. Pretenses are for pretenders. You’re just trying to become a better version of your genuine self.
