Hi
Could anyone explain to me what "to live one day at a time" means.
Thanks in advance :-)

To live without making big long-range plans or/and setting long-range goals.
Tending to affairs immediately necessary rather than being preoccupied with what
may come next month, a year from now, when I turn 50 or when I retire.
