For those picking up emacs for lisp development, I'll add another piece of terrible advice: enabling paredit mode.

I think these all have a similar theme to them "I am more productive now since I have turned them on, so I wish I had switched sooner" but they ignore the fact that each of those things adds friction to learning the basics, and at some point people will just nope-out.

Yes, good point. Learn how to balance parens with rainbow delimiters (if anything) and, once you you're comfortable with sexps, give paredit a try.
