It is completely subjective. You get to decide what it means to you.

To have crushed your enemies, to have seen them driven before you, and to have heard the lamentations of their women.

I believe Carl Jung said that a full life contains work, love and play. A sense of purpose and connection to others are vital components to my way of thinking. Mother Theresa said, ”‘Not all of us can do great things. But we can do small things with great love.” This is what I strive for and don’t always achieve – a rich connection with others, kindness, and creative and fulfilling activities. I worked when I was younger and I raised a family and I have seen some of the world so I would say I’ve lived a full life.

Engagement with activities and people in real life is one key factor, IMHO.

Similar to enjoying a meal till you are full and satisfied. You just can’t take anymore!

Seriously, I think it is to align your goals and values with your actions, leading to a sense of purpose and fulfilment. In a word, reaching self-actualization.

Everyone is different. Each and everyone has a different sense of what fulfills them in life.

@janbb has written a fine answer. My individual situation is different from hers, but the underlying sense is the same. I would add that a full life includes hardship and perseverance through those difficulties.

If, at the end of your life, you don’t feel any regrets then you have lived a full life.

I Shall Not Live In Vain
Emily Dickinson

If I can stop one Heart from breaking
I shall not live in vain
If I can ease one Life the Aching
Or cool one Pain
Or help one fainting Robin
Unto his Nest again
I shall not live in Vain.

Did shit.

Did good shit!
