Thích Nhất Hạnh, who passed in 2022, wrote in The Art of Living
We should not be afraid of suffering. We should be afraid of only one thing, and that is not knowing how to deal with our suffering.
The Buddha exposed in his Four Noble Truths (approximately a hundred-handful of years before The Christ walked the Earth (that's about 26 centuries ago!)) a basic understanding of existence as conscious biological organisms.
His First Noble Truth is that life is 'dukkha', or the Truth that life is suffering.
The "truth of suffering" part has been repeated and meme'd into dullness, because we all know just how very real the pain of living can be.
'dukkha' is a Pali word (a variant of Sanskrit), and it (as all words in all languages seem to do), means more than one thing, given the proper context.
It may help one to interpret 'dukkha' to mean "incapable of satisfying" or "not able to bear or withstand".
Of course, it probably does not really help for us to sit here and debate centuries-old etymology!
Pain is pain.
I guess what I really mean to say is that to get past the obvious truths of suffering, pain, frustration and grief is to understand that occupying one's awareness is just part of a process.
A process that enables us to observe our existence in this Universe in a different light.
A process that takes time.
In the times when I was at my lowest energies--and seemingly without hope--just one minute, hour or day of living that led me to a space where I was able to gift another human with the means to a smile, some hope that living is not pointless, or the energy to try living a little bit more . . .
I ultimately found satisfaction.
If I were to live for another hundred years, and all I could say at this end is that I made just one person's day brighter, in even a small way, I would consider my Life fulfilled :)
That "One Person" is waiting for you somewhere along your timeline.
