Binbrain, you're only 21....don't be heart broken or give up. The first time I tried for ATC stuff I was 24 and did Eurocontrol. I got to the interview and they failed me...I believe it was because I had just moved to Europe two months before. At 24 I had no chance of attempting for Eurocontrol again....I moved on and found NATS. Now I am set to begin the college in Feb.
Keep you head up and stay positive. I truly believe that is the biggest factor in making it through all of this. Stay positive and you will find a way to achieve what you want.
