Ut clauses of result are excellent for saying "so ___ that". But what if I wanted to reverse this and say "not ___ enough to"?
For example, tam strenue laborābam ut epistolās centum scripserim means "I worked so hard that I got one hundred letters written". What if I wanted to contrast myself with Pseudolus, who didn't work hard enough to get one hundred letters written?
(Note that I'm not looking for a simple ut…non, which to my understanding would be something like "I worked so hard that I didn't get one hundred letters written". I want to negate the working hard, rather than just the writing.)
