That’s a real killer of a lesson. It beat me up decent. It’s there, and you can find it. Don’t let one thing you can’t do (yet!) Get in the way of all the things you CAN do.
Remember, some of these lessons are meant to be difficult. Consider it stretching your ability. If something is a challenge that you can’t meet right now, that doesn’t mean forward progress ends. The really nice thing about b2b is that it’s at your pace, no one demanding you get anything. And it’s also shame-free. No one here thinks less of people when they struggle some with something new, that’s not how learning happens.
Would it be nice to Just drill all the lessons in order, at speed, dead perfect? Certainly. And I don’t think anyone here would claim they did.
Go at your speed, focus on fundamentals. Learn what you can where you can. And above all, have fun and feel good about playing!
Don’t stop making noise, keep at it. It’s there.
