One of my favorite proverbs is “Make hay while the sun shines”
It means that
"do not leave any chance when it comes"
It's often said when
we talk about getting a chance to do something.
There is a similar proverb in English is
"Tide and time wait for no one."
I like it because I think it is very important for my daily life and I think that a chance is not given to everyone all the time,
so you should grab any chance before it will never come back again.
