If at first, you don't succeed

Several cliches exists now,
Success and its interpretations,
Trial not once, but a few,
Abilities, a part they play,
Outcome, much less they say.

Effort is the measure I hear,
Lack of, can be failure,
To each, his own definition,
One's poison, another's food,
Ultimately much chased after.

If at first, you don't succeed,
Another try will make it so,
If again, not up to par,
Another one will take you far,
Thus goes the age old adage.
