YOU SAID:
I've been working and putting in all my time
INTO JAPANESE
私は仕事をして、すべての時間を費やしてきました
BACK INTO ENGLISH
I've been working and spending all my time
INTO JAPANESE
ずっと働いて過ごしてきた
BACK INTO ENGLISH
I've been working all my life
INTO JAPANESE
私は一生働いてきた
BACK INTO ENGLISH
i have worked all my life
INTO JAPANESE
私は一生働いてきました
BACK INTO ENGLISH
i have worked all my life
That didn't even make that much sense in English.
