"Be careful with what you wish for because. you might just get it"

Song lyrics and other media has this to say: "Be careful with what you wish for because you might just get it".
Wether coincidentally or not, it is true that some of what you wanted would happen for you.  The unfortunate thing is that it would happen with an unfavourable twist.  Regret is the recourse but life must go on.  Yes, BE CAREFUL!
