You know how, after someone you know passes away, for the next few days/weeks/months you feel this deep connection to life? Why do we have to cycle in and out of a personal realization that we exist, only when people stop existing?
Embrace it as often as you can, say it to yourself every morning, make it your mantra “I exist!”
I think if we begin to accept both that we exist, and that one day we will not exist, we can become more appreciative, loving and live more fulfilling lives.
