The ability to sustain prolonged physical or mental effort.
How long have we tried before we got tired and gave up?
I think being tired doesn’t necessarily mean giving up. And stamina is probably how long one can last being in that ‘tired’ state. That tried-and-tired state.
But I guess everyone has their limit. And we can all try so hard. Til we run out of possibilities and run out of whatever fuel that has kept us going.
One day, we will all cease and stop when we realise whatever that has kept us going has been spent. Perhaps it is time to go to a better channel, or a better medium out there, to achieve the same goal. Or perhaps giving up is the end.
Just like our body.
There is only so much one can do, so far one can go, before we perish.
