Why?
I am a writer, therefore I write.
You maybe a painter, therefore you paint.
Simple.
A writer might see stories where ever they look.
A painter might see the colours and textures around them.
A musician hears the melodies in conversations and noises of life.
The ‘this’ is whatever it is you are doing creatively – imagine it is a blank line and you need to insert your creative project or endeavour.
Why you write, or draw, or play an instrument, might just be because it gives you joy.
Or it might be because it is your career, or you want it to be your career.
Both reasons are fine.
But both have different expectations of you.
Realising this might help you save time in the long run.
Know why you are doing your creative thing and act accordingly.
One is a job and needs to be treated as such. The other has wriggle room and can be the subject of whim.
