After time to reflect, I think the most important things for the enjoyment of Terraria are:
Do not lock yourself into a class and refuse to use anything from other classes, it just makes earlygame feel awful and emphasises the weaknesses of a class that you are arbitrarily creating, this isn't an RPG where you are locked out of other gear, so just use it
Deprioritise progression, and focus on enjoying building and exploring, and building fun stuff, because Terraria is a building sandbox too, not just a combat game
Don't play Master or other difficulties just because people say it's the right way to play. Pick what level of engagement you want. Want a casual experience for sandboxing? Try Journey, and just don't use the cheats if you feel like being legit.
