Practicing drawing for an hour a day will improve one's drawing skills. Indulging too much in the company of women can cause unsteady hands, making drawing more difficult. A poet's role is to depict general characteristics and prominent features of human nature that remind everyone of the original subject.

1. I can promise you that an hour's practice a
day ... will give you sufficient power of
drawing faithfully whatever you want to draw:
of which hours, if you have one to spare at
present, we may as well begin at once.
Do not fail, as you go on, to draw something every day,
John Ruskin, The Elements of Drawing for no matter how little it is it will be well worthwhile,
and will do you the power of good.

There is another cause which, if you indulge in it, can
make your hand so unsteady that it will waver more and
flutter far more than leaves do in the wind, and this is
indulging too much in the company of women.
Cennino d'Andrea Cennini, The Craftsman's Handbook
The business of a poet, said Imlac, is to examine not the
individual, but the species; to remark general properties and
large appearances. He is to exhibit in his portraits of nature
such prominent and striking features as recall the original to
every mind.
Sam Johnson, Rasselas
