The key to a well-lived life isn't a laundry list of do's and don'ts, but a willingness to examine one's own life to see what is working for them and what isn't. Then, it's having the gumption to try something new, make a change, and follow through with the flexibility to reexamine, reassess, and try something else again and again and again throughout one's life.
It's also the ability to realize that to everything there is a season. Just as the leaves are changing and the weather turning colder, our bodies and souls go through periods of turning inward, resting, and even dying a little bit, just to grow branches that are longer and stronger with flowers and fruits that are more beautiful and succulent than before, if we are willing to allow it.
Life isn't static and things change. There isn't a master blueprint of "this is how my life should be" from the moment we arrive on this earth until we depart from it. And if there was...what fun would that be? A life worth living allows us the non-attachment, freedom, and confidence to change, grow, blossom, and bloom...then to die, rest, and be reborn again and again and again.
