mmm. spiderman you say you do not enjoy fixing and building things. Dont hold me to this but isnt having good problem solving skills an essential part of being a pilot. personally there is nothing better than working at a maths question for 20 mins and finnaly solving it. maybe others are right, maybe take an apptitude test as well? that may give you more of an insight into your suitability. as you may see my spelling is pretty appauling and i wanna be a pilot as well. i dont know if that would hold me back but hey i can only find out. anyway good luck in what ever you do choose to do.
EDIT: In refrece to colour difficency, that will be picked up when you do your class 1 meical. the caa do a lantern test which im proud do say despite my very very slight colour difficency between red and green of all colours, i managed to pass it. (the lantern test that is)
