The easiest and fastest way to get everything installed is ghcup https://www.haskell.org/ghcup/

As for being successful, there are several nice books, and several active forums. I've gotten good answers on the Libera IRC network #haskell channel, and on the Haskell matrix channel #haskell:matrix.org

If you want to get started without installing anything, there's the exercism track: https://exercism.org/tracks/haskell

I've heard good things about Brent Yorgey's Haskell course ( https://www.cis.upenn.edu/~cis1940/spring13/lectures.html ) but haven't tried it myself.
