Physical
space; a room where you won’t be disturbed, where everything you need
is at hand. Where you feel comfortable. And mental space; turn on
airplane mode, forget about your troubles. If you can’t, you won’t be
able to write. That’s fine, but get help if this lasts too long. (read more: https://songwritingguide.tumblr.com/post/149280180666/time-space-and-energy)
Your
goal is to finish a song. Not a great one or even a good one. Just a
song. It’s easy. Like A B C, 1 2 3. Just some chords and a lyric. You
know you can do it.
You
are not in charge of your quality. Only your quantity. At least 10% of
what you make will be pretty terrible. You have to create that 90% to
get to the good stuff. Toughen up your ego and learn to love writing the
crap. How? See point 5.
Motivation
comes from creation, not the other way around. You will usually not be
in the mood to write. Do it anyway. Just create. Again and again. Good
work will come.
