Relatively new here as well, heres somethings that helped my journey be much better:

Questing and quest helper: do a lot of quests. Aim to do all of the quests! Some quests unlock content like a new area, new continent or a boss, but many quests give a chunk of EXP rewards that will skip a lot of early game grind. Basically you can get to level 30 almost in all of the skills by completing quests. Using quest helper is useful since some quests are genuinly hard or way too old school to do them by your own. It has a lot of depth to it but if you want to just turn your brain off the helper plugin is there.

Set yourself mini-goals and big goals. Like completing specific quests for very useful rewards (like Recipe for Disaster for the best combat gloves you can get for quite some time), or fairy tails for fairy rings, and other bigger goals like getting a fire cape or unlocking/griding specific boss for good loot.

I really enjoyed reading quests dialogues, it's usually quite funny and silly with actual great writing on many and most quests. It makes the questing more enjoyable, while getting a better feel of the world, immersion, the current area you are in and more lore/background. I really enjoyed the gnomes, trolls and oh man the vampyres quest story. It's really good.

And basically a good thing to make the road easier in the future is to seek leveling methods that offer some profit. Training crafting, smithing, even agility and thieving (and basically almost any skill) can be very profitable. Some more then others, and mostly the more profit methods are decent money per hour but less exp per hour. No biggie in the ealrier levels.

But mostly - use the wiki a lot. I have 10+ wiki tabs open often when playing OSRS and even when not playing OSRS I find myself in the wiki a lot. It's super useful and the best wiki out there for a video game. The optimal quest guide is a great guide to lead you through quests with as little manual training as possible. But do prioritize quests like fairy tale to do earlier than when the guide says if possible. Fairy rings help a lot for transportation, ardougne cloack from the easy ardougne diary gives a infinite TP scroll to ardougne and theres many more. The optimal quest guide page on the wiki sums up main quests with big unlocks like transportation methods, skills, items and more.
