It’s usage in my slang: if anyone says to you that you would be unsuccessful or you would be a failure ,etc.
Just tell them “Kachifonu”
Meaning good night, let’s see what tomorrow holds.
And only say this if you know who God says you are!
Only If you know the God you serve!
So yes confidently say to that problem or struggle you’ve been going through, KACHIFONU!!!
Weeping may endure for a night
But Joy comes in the morning!!!
