Talent

Talent is elemental,
it has isotopes,
it depends on neu(t)rons,
how much you have.

                        Talent is learned,
                        earned by hard work:
                        it depends on learning
                        from others’ mistakes.

Talent is hereditary,
it is in the genes:
it depends on relatives
being quite famous.

                        Talent is pointless,
                        it doesn’t help you:
                        it depends on someone
                        recognising it.
