This is a great advice. Erlang was the first functional language i really learned and i can definitely attest to the pains mainstream developers go through when switching the paradigm. In fact with Erlang you're jumping two paradigms at once - functional/immutable and actor model of concurrency. Eventually it clicked and i think learning Erlang was single most impactful thing on my way to becoming "a better developer". Throw away your best practices of procedural/oop world and unlearn your optimization tricks when diving into functional/immutable. It's a totally different way of thinking about problems.
