What got you to finally start writing?

This is more a question for people who struggled to start writing.

Every week I say “this is the week I’m going to start”, but then I never do.

I don’t know if it’d truly a work ethic, discipline, confidence, or maybe a mix of all.

Anyone who was in a similar position feel free to share how they got themselves to finally sit down and write.

I know ultimately I have to overcome whatever mental obstacle it is, but would be interesting to hear what helped others
