'spankracht' is a physics term for the force that occurs when you bend a bow or pull a string. used here figuratively to describe the mental ability to be sharp while doing your job. maybe 'resilience' is a better term?

aside from the typo in physical, the last sentence is not 1st person plural, it contains infinitive, translating with 'enter into' better conveys the sense of planning without making guesses about who or how many people are subject(s)

It's work situation instead of "worksituation"; two words.
I agree with Nego on the resilience.
