Set shorter tasks and deadlines

Short deadlines not only make you work harder to finish faster, but they also train you to reach the deep work state constantly. Also, some new tasks may add up to the estimated ones, so you may need those extra hours of work every now and then.

Make every task simple. Each time I have to make a work call, I convince myself it will last for a maximum of 10–15 minutes, even if it never does. In this way, I nullify any barrier my mind develops against that task.
