spend the rice
'Pasarse el arroz' is a colloquial phrase in Spanish, not literally related to 'spend the rice'. Instead it is a metaphor about the optimal moment to cook rice, after which it may not be good anymore. Often used to jokingly refer to a person, especially a woman, who has passed the 'ideal' age to get married or have children.
I don't want you to let time go by because it's already very late.
This phrase suggests that the individual should not miss out on an opportunity as time has already advanced.
If you keep waiting, you will let the moment slip away and lose your chance.
This example conveys urgency, implying that delaying action will result in missing an essential chance.
I was about to let that project slip away, so I decided to act quickly.
This statement illustrates the importance of taking action before it's too late, indicating a sense of urgency in project management.
