I pick up a pen but don’t know what to write and express it in classical Chinese

I was about to pick up the ink when I started writing, but there was no trace left when I started writing. My heart went blank, I don’t know why.

I want to pick up the pen and write something, but there is nothing under the pen. There is a blank in my heart, and I don’t know the specific reason. What this poem describes is that people have no inspiration. A life that is too comfortable makes the mind and body lose their ability to perceive. The numbness to life makes the brain go blank. People cannot feel life and have no inspiration when creating.

The most embarrassing thing for a scholar is to forget to write when he picks up his pen, or forgets to say something when he is proud.
