We live in a society that fears death, and we're raised up to believe death is undesirable... "bad".
Imagine what it would be like to have grown up in a society that didn't fear death! There are such people who celebrate with joy. They honor the person who died.
Since we've been brainwashed and have this ingrained negative viewpoint and emotions regarding death, choosing to change will be challenging, but it can be done. We can still grieve the loss of the one we love simply because we miss them.
My personal viewpoint is:
Live life as though you will die tomorrow and all the bullshit falls away.
You will know who and what's really meaningful to you.
In the meantime, live life to the fullest extent of your being.
Take the good things and be glad.
Take the troublesome as challenges to overcome and grow character.
Love yourself and extend that love to others who are able to accept it.
Honor your friends by remembering the good times with them.
