Here's a phrase that stops talented people creating:

"just sit down and"

as in:

I want to just sit down and write

I'm going to just sit down and film

Let's just sit down and make a plan

NO

It's a myth

You're busy

You'll never find time to "just sit down and" do anything

That's not how it works.

Believing in this magical future blank space will stop you sharing your work.

Instead:

Draft post ideas on the fly
Voice note yourself on long walks
Doodle when you're waiting in line

Stop waiting to "just sit down" and do things.

Start now.
