I reckon the best way to improve any little shortcomings in spelling and grammar (everyone has a blind spot somewhere) is to read the correct version so many times that it becomes second nature to use that. Reading a lot of decently-written books helps, and so does good but not harsh teaching from the start of school.
Some people absorb spellings more easily than others, perhaps because their brains are more visual, but others find sayings like "I hope you can hop on one foot" or "Here is almost there" useful.
Greatnan was not picking on anyone - I have seen loose (to rhyme with goose and moose) when I thought the poster meant lose (to rhyme with booze and shoes) but I could not tell you where so no-one needs to feel got-at.
Should a loose goose try to lose the booze? No, because that will just make it type "looze" - what a daft language!
