Now then young smoggy!
Continuing the theme of advice, I would go with some of the earlier posts recommending languages. At present, you may have noticed the job's market is pants, but there are still vacancies cropping up from time to time. Some of these are for operators on the Continent rather than UK based outfits, and they almost invariably specify some language requirement. Straight away this will rule out many UK pilots as language skills are notoriously poor over here (and I'm one of them).
In a highly competitive employment market, you need to make yourself as employable as possible, and good language skills (whether from formal qualifications or otherwise) will be a valuable weapon in your armoury. Everybody seems to leave school now with umpteen A*'s in Maths, English and so on, so doing well in these alone will not set you apart.
Additionally, think long and hard about extra-curricular activities. It's not all just about qualifications - they serve only to get you through the first level of filtering.
