Imma say something super-flip, not because of the question (which is great!) but because I can’t help myself:
Learn the alphabet, but only up to G.
I want to be able to eventually sight read music, something I could kinda do as a kid playing violin. I definitely knew (and still know) the names of all the notes in first position on the violin fingerboard. It’s a little frustrating to me that I can’t do the same thing on the bass yet, but my brain’s RAM and ROM have a LOT more going on in them now than when I was 11. Sheet music was the only thing we used as well - no tabs!
I made this chart and hung it next to my desk. I did it by hand, in different colors, to help create a specific memory of physically making the chart, which I think is helping.
So I guess my actual, non-flip thought is to write out or draw the notes, saying them out loud as you do it. And as @jwatts777 mentions in his post and @JoshFossgreen has us do in the lessons, say them out loud as you play them.
