Hello!
Sorry I've been quiet for awhile! I've been consumed with a few other projects, but I should be offering thoughts and advice more regularly once again!
To start off, I came across this excellent metaphor for what it is to be a musician. It talks of incremental growth and skills sets in the context of swimming, but it applies to us and our skill sets too!
I found it by being a part of the 'Atomic Habits' email list. If you would like to check it out, it's under the '2 Quotes from Others' section, number II
FYI: I have NO affiliation with James Clear or Atomic Habits and this is NOT an affiliate link. I just thought it was good info.
