Hello Eldrix, welcome to the community forum. I’ve also been following Justin’s course everyday for a year (after 30 years of advancing beginner guitarist status) and in the middle of Grade 3. I looked at your LL and am in awe of your 4 hour per day goal. You might consider Justin’s advice to make sure that half of that practice is something that is fun for your to keep you motivated. Of course, you may find all of your practice to be fun and exciting. I did look back at your LL practice schedule and saw that actually guitar playing was about 2 hours 25 minutes and the rest was ear training, theory and voice training. I can’t manage more than an hour in a day and usually 30 to 40 minutes, but try to practice every day. I look forward to seeing your progress in the LL.
Hello Eldrix.
Welcome to JustinGuitar and the Community. It’s great you have found Justin’s website. He offers structure and a sure path to follow from the very beginning. Thousands and thousands have learned using his lessons. Going back to his beginner lessons and self assess to see if you have any gaps, or bad habits to fix is a great approach.
If you need any help with a lesson specific question or with any general guitar learning question then do not hesitate to ask. There are many good folk here who will happily offer help and encouragement to those coming up behind them on Justin’s Beginner Courses. They embody and carry the pay-it-forward ethos we have nurtured for many years in our community. There are many old hands too who have years and (hopefully) a bit of wisdom they can bring as they give their support to those hitting the road blocks - which we all do.
Just ask if you need anything.
Cheers
