@jonmutivito the fundamentals of sculpting and mesh modeling basics courses are great and are for blender 2.8 already. They are great for beginners.
I totally can relate to your enthusiams and nervousness. Just remember to take a breath, and take 5-10 minute breaks between some heavy learning sessions every half hour or so. Go reward yourself for that hard earned learning. It will bring energy back to keep going each day.
I’ve been using this hobby for 2 years almost (only in my limited spare time as a dad of 3 and an engineer). I’m still kinda a beginner at a lot of things but I have stuck with it and I can see that I am improving,
