What differs luck, fate, fortune and destiny?
Luck: Luck refers to something happening at a given point of time out of sheer chance/surprise. An unexpected and unusual (having lesser probability) outcome of an event. Example: Lucky. If you win a lottery. If the catch is dropped by a player who usually does not drop any. Fortunate: Fortunate word is usually used for a situation in which a sequence of events has happened so fast enough that could not be recorded and whose effect is going to last for a while. Used when some unfavorable outcome has been avoided for whatsoever reasons. Avoid bad luck. Example: If you survive an accident. Fate: Negative connotation. When something grossly wrong happens out of control of human intervention. Destiny: Grand design in which the events unfolds in a way to take take you to your destination without your awareness. Now food for thought: what would you say to your parter: Am I lucky to have you as my partner? Or Am I fortunate to have you as my partner?
