When you feel stuck and don’t quite know what to write, instead of shying away from it, follow it.
Start typing and just see what happens.
Don’t focus on how good or bad it is. Don’t focus on whether it’ll be worth sharing online or what people will think. Just write and then write some more.
Keep going until the words start to flow with ease. It might get easier after a few sentences or a few hundred words but keep going and just write.
When you finally decide to stop, you might find that you love what you’ve managed to write but that isn’t the goal or the purpose.
The purpose is to write through the ‘writers block’ because doing so teaches you that maybe it’s not as big of an obstacle that you think it is.
