It is wrong to ever split an infinitive. Contractions aren't necessary. Do not use a foreign word when there is an adequate English quid pro quo. One should never generalize. Tell me what you know.
Comparisons are as bad as cliches.
It behooves you to avoid archaic expressions. Avoid archaeic spellings too. Understatement is always best. Exaggeration is a billion times worse than understatement. Analogies in writing are like feathers on a snake.
