That Pivotal Moment
There is no such thing as "the right time" when it comes to developing your talents in Excel. You are always on call as the swiss-army-knife of information. Today a financial analyst, tomorrow a visualization specialist... within each role you are consistently relied upon to evolve your talents at a moment's notice. So, throw away your abacus because you're about to learn one of the best tools for your arsenal. I've seen people spend hours writing COUNTIFS that could be replaced with a few drag-and-drop actions. Pivotal, indeed.
