tense.
"I OFTEN LEAVE off sedentary work after writing a few dozen words and go to the courtyard to take a look at the flowers ,watering them and moving about the potted ones.Then I WILL return to my room to write a bit moe. I WILL go through the same back-and -foth process again and again ,thus combining mental with manual labour ."
In the first and second sentences," leave off work "and "return to my room" are actions of a sequence.
Why to use the present tense in the first while the future tense in the second sentence?
