The best luck always happens to people who don't need it.

When a person is destined to get something, no one can take it away & s/he is going to get it anyway; but if not, then no amount of own effort/energy or none can make it to stay to him/her and the same thing will go to some other way.

it takes only a moment for the destiny to flip over

Oh, I am fortune's fool!

Lady Luck only favours gentlemen.

For what blessing may a man hope for but
An immortality in
The loving vigilance of death.
