k？ Mpfen = fight, struggle, effort. Mein Kampf written by Hitler was translated into Mein Kampf.

Gas geben = Step on the accelerator of the car to provide more fuel for the engine and make it stronger. Its extended usage is to refuel and work harder.

According to the original words, the artistic conception is to hope that the subject will work harder to do things well, even at the expense of body or spirit, so it should be expressed by verbs.

Putting "refueling" before "struggle" is more in line with German habits.
