There are many things which can a writer afford not to have.
If you don’t have a computer, you can have a paper and a pen.
If you don’t have an internet connection, you can go to a coffee shop.
If you don’t have an office, you can lock yourself in the toilet and write.
If you don’t have the time, you can wake up earlier and write.
But, if you lack health, you don’t have the tools for writing.
