Thanks for the reply guys, but would it be a good idea to start my flight school now, while I'm young? Air cadet may be an option... Thoughts..?
I'd concentrate on school and extra-curricular activities for now. Flying training is like taking on an extra year 12 subject and to do it justice is very hard.
I am fairly sure if you look back in my post history about 7 years ago you'll find I started a thread very similar to you. People advised me to relax and go slow. I didn't listen. I'm not unhappy but I do look wistfully as opportunities outside of aviation I have missed.
At the end of the day it's what you will hopefully be doing for the rest of your life. Take your time and enjoy the journey.
