It makes 100% sense to me that we should take pleasure in little if little is all we have. Seems to me that it's very hard to quibble with that.
The tougher rhetorical issue seems to me to be "Is it inherent within the expression of that thought that little is 'good enough' and therefore we should not act to seek more than little?"
I think a lot of people jump to that conclusion, perhaps influences by Stoic and many other sources of ideas, but I do not at all think that conclusion is necessarily implied, and I get the idea that most of the ancients and all of the Epicureans would think such a suggestion to be absurd, because it is natural for all life to pursue as much pleasure as is open to it to obtain without undue hardship.
I write this because Don if you see anything in that article or Horace which bears on that subject please bring it up. Epicurus makes it plain in the letter to Menoeceus that we do not set our sites on "little" but on "pleasure" , and I bet there are other instances of the same thought out there in other texts.
When Horace said "Seize the day" he didn't say "Seize little" or "Seize only what will keep you alive."
