Whilst I can fully sympathise with your youthful keenness ( it wasnt that long ago for me!) I have to agree with the two previous respondents.
By all means keep up a healthy interest in all things 'aviation' as it will never do you any harm, but the priority MUST always be a sound academic background. Sounds dull and boring, but I promise you wont disagree in a few years time.
You will make it....I can tell by the mature posting that belies your age.
