You probably need to curb your expectations at this early stage of playing. One thing worth mentioning is that, even though you’ve completed a course called Beginner To Badass, it doesn’t necessarily mean you’re a badass.
Any instrument will require a MASSIVE amount of practice and it can be several, or many, years before you feel even slightly accomplished. That’s just the reality of it. You can’t rush the process. For that reason, you need to be practicing material that is at your level. That level is easy to find because you just try playing different things until you know what you can and can’t play.
Online courses are useful but they are TOTALLY dependent on you doing the work yourself. I say this as creator of TalkingBass - an online education platform. I know that the student has to approach their learning as a self-taught/tutor-taught hybrid. This can make things a little tricky from time to time because it’s down to you to seek out the study that is right for you.
I’m friends with both Josh and Scott (SBL). Scott and I went to music college together and come from the same town. They are both phenomenal at what they do. SBL is a great platform. You will just need to more direction to the correct material for you level.
One thing I do like to do with TalkingBass is discussion with anyone looking to join up. I’ll answer questions about the courses and ask for details of your level, experience and goals. That way I can direct you to right course for you (or the correct progression of courses).
It sounds like a little direction and guidance would have helped you getting started at SBL. Some people don’t need it and just jump in successfully, but obviously that’s not always the case.
As you might have noticed, the online bass space is a very close knit and friendly place. Myself, Scott, Josh, Phil Mann, Janek, James Eager, Daric Bennett, Ariane Cap, Joe Hubbard, Luke at Become A Bassist are all buddies. That community is something I really love about doing what I do.
