The biggest win for me was having the opportunity to use Alteryx and become an "almost" SME for our team out here, starting an Internal User group and of course becoming Alteryx Core Certified!
Alteryx has absolutely changed the opportunities that are available to me- and sadly I recently accepted a new role within Charter- where they don't (YET) use Alteryx, so for 2019 i'm hoping to continue to participate in the Alteryx beta program, the community and keep my Alteryx skills growing as I know it won't be the last time it makes an impact on my career! (and maybe convince my new team to pick up the tool :D)
@ADerbak- not sure I can keep up with your goal of 50 challenges...but i'd like to say I could challenge you with half that? so 25 challenges is the goal!
have an awesome year, and hope to still take part in the discussions on here!
