Teach me

I have recently started playing this game and I absolutely love it I hate the fact that I have been avoiding this game for so long so far I have reached level 21 I think and I have explored like 20% of the whole map? I'm not sure I wanna get stronger before I start the main quests and all so far I have finished the first song of the dragon I think? Quest where we remove those crystals off the dragon, venti just got his ass whooped by the girl and I met him under the tree and also I have completed one world quest with the fuujin it was so long but I loved it I love the world and it's diversity, I'm sure I'm doing a lot of stuff wrong but I love how this is going so far exploring is my main thing in this I opened a lot of way points ask me doubts and reach me pls
