this goes for all creative efforts tbf:
if you can't sing good, sing bad. if you can't write good, write bad. make no first draft, repeat the same words over and over again, skip whole sections because they don't spark joy.
it's good to be proud of your work, but there's value in just making for the sake of making. and if you focus on just having fun, that bit of improvement with every work will just be a bonus.
the world has enough critics. it desperately needs more people creating what makes their soul sing, regardless of whether it sings in tune
always remember that amateur stems from the latin word amare witch means "to love, be in love with"
being an amateur means that you love what you do
