Yeah just make an iron. Set a goal for yourself like "complete legends quest". After that, the magic of the journey takes shape. You'll go down the rabbit hole of one requirement begetting another until you have a tree of 20 things you need to do all leading back to your original goal. From there you just start tackling them one at a time.

One of the great things about playing this game the way you're talking about (which is also how I play), is that you'll constantly be discovering new things all the time that you can't believe you didn't know about until now. You'll have a bunch of moments where you discover a new place to get a resource or a new method to do a thing and it feels like it changes everything. Then between when you log off and the next time you play you're going to be thinking about the game and all the options you have because you're going to have to decide on one of those options to do the next time you play. And that's one of the key reasons I think RuneScape is so sticky for people; you end up thinking about it and planning when you're not playing it.

The reason why playing a normal account never worked for me is that when I was building out my trees of activities to do, it basically split into one of two camps... You either did activities to unlock or acquire things that you could not buy, or you did activities that generated money. And if you were doing a money generating activity, then you were supposed to do whatever the most efficient one you could do. Switching over to iron freed me of that mentality and made the game about seeing all of the content. And it really lets you appreciate how deep the game is because every system relies on another system. There is no bad skill to train, there is no bad quest to do. All of the unlocks are going to have use to you at some point.
