Yes, also seconding that you don’t necessarily need to work through a million textbooks to get started. I would say that at least a base level of Genki 1 and 2 are a good idea, but you can start reading before you’ve finished them; I certainly did.
If it’s manga you want, definitely check out the Absolute Beginners Book Club to help you get started reading!
And I’d also recommend browsing the study logs category on the forums to check out other peoples’ learning routines and methods!
Welcome to the forums and happy studying!
