@For_the_moves Same as growing your vocabulary. Remember, words (or functions) = ideas. the more you know, the better you can think.

That got me thinking. How many functions should you care to learn?

My answer
Simple. Think of functions as words. The more you know, the better you can communicate with Excel. It is just like building your vocabulary. That said, there is no point memorizing every last one of them. And let’s be honest, its not like you are going to suddenly start using ACOTH(), BAHTTEXT() or COMPLEX(). But learning just SUM() and IF() is going to get you in to trouble quickly. Go beyond the basics and pick up necessary formulas to become awesome at work.

Note: It is a long weekend in NZ (labor day). Although every week is a long weekend for me (I don’t go to work, I am happily self-employed). That said, this one is special as kids get an extra day to enjoy. So we are going on our first ever overnight tramp (hike + stay in woods). We are heading to Rimutaka forest park. Next transmission will be on Tuesday. Enjoy your weekend. And if you get bored, you know what to do.
