We use some
and any
when we are talking about limited but rather indefinite number or quantities.
In general, we use some
for affirmative sentences, and any
for negatives and questions. Both can be used with countable and uncountable nouns.

Did Jane buy any flowers? - No, she didn't buy any
Some
can be used for questions, typically offers and requests, if we think the answer will be positive.
Would you like some tea?
Any
can be used in the meaning "it doesn't matter which".
You can take any bus. They all go to the centre (=it doesn't matter which bus you take.)
We use enough
to indicate sufficiency, while in negative sentences it means less than sufficient or less than necessary.
