I second following the optimal quest guide! Quests are a fun way to experience the world and the guide is a good way to set goals for quests and skills. That being said, don’t be afraid to stray from it if you want! If there is a skill or other piece of content that you’re digging just roll with it. The best part about this game is that there is so much to do and so many different ways to experience it! https://oldschool.runescape.wiki/w/Optimal_quest_guide
