In these 3 words, people talk more about destiny and mission. It's understandable, because it's... important. Fate is the future, is destiny that everyone wants to know but almost cannot know, cannot control because it belongs to an invisible, distant and giant universe. In other words, it is passive, objective.
Mission is also a matter of the future, but it is somewhat more specific. Mission is something people look for, can be seen very early, but sometimes it takes a long time to have a touch point. But when you are engrossed, yearning to know destiny and mission, sometimes people forget about life - the most important factor to have the remaining 2 words. Life means life.
In the process of growing up, the search for a mission is understood as aiming for something great, something noble. It can make people feel valuable, have ideals in life, or sometimes just to fill the gaps inside. So they forget to take care of life, take care of the self as a fulcrum for the mission.
That means, these 3 words destiny do not exist independently but always have a correlation. We take life (living). Impact and be tested by destiny (circumstances). Then wake up and find a mission (living ideal). When these 3 "deaths" are merged into one, people reach a state of freedom, using finite life, going through ups and downs of destiny, to complete a complete mission.
Life may be long, may be short, but when you have passed the joy and happiness or the storms of fate, the mission will leave bells ringing, exceeding the limits of time. And he thinks, when the 3 words "fate" blend together, people will freely create their own picture of life, without regret at the end point.
