For me, learning Elixir did this. I was going to change careers into commercial real estate about 9 years ago and then I binge read “Programming Phoenix” over a weekend.

Walked into work Monday morning, bleary eyed and told everybody, “This is the solution. This is how you build rapidly and bypass all of the long term maintenance issues that we always have to fix in every other codebase. It makes the hard things easy, it makes perfect sense and it’s FUN.”
