Once you see the beauty of data, It's hard to look back. Only remains you and your thirst to find new facts and knowledge. Some get stingy on modeling accuracy, some delve into the data-selling (presentation), some swim inside the data pipeline and ETL, and some are the perfect servant of the data(data serving). I am the chef. I clean the data with passion and keep it flowing (ETL), I find a perfect recipe and taste it continually (modeling and testing), I care much about my customers and their testes (analytic translation) and serve them the best dish to enjoy (presentation and data servine). It is an additional joy when I apply the data knowledge to finance, telecome, or advancement.
