Point in Time

Is there ever, a point in time,
When you would say, "I've had enough?
Seeing the change, to dependence on me,
Gradually, creeping in, all of the time,
Will strengthen resolve and make me tough,
To deal with those, without having time.
These issues, make a coward of me
And resolve them, I most certainly must,
Before my body and mind, turn to dust.
