If you have the capacity to add something else to your study routine, I’d recommend Pimsleur. Genki is fine for beginner grammar, and Pimsleur would reinforce that with more listening and speaking (something self-learners sometimes have a hard time getting enough of). If you do the writing exercises from the back of Genki and look up additional vocab that’s relevant to your life, by the time you finish Genki 1 you should have more that enough grammar to hold simple conversations, so that might be a good time to try jumping into the discord group.
