Hi.
First, only you can assess if this field is right for you, but from the sincerity of your message, I would say to go for it.
I had the privelage of trying out for ATC when I was on an aircraft carrier in the 50's, and it was fascinating then, so I can imagine how exciting it hasto be for ATC"s now.
No matter what service you join, you will receive a training second to none. I will take a moment now to say to all ATC"s no matter where or when, "Thank You" for providing a service that makes it possible for me to visit my children and grandchildren in a safe and secure environment, you guys are the best of the best and I salute you.
To you, go get that training and enjoy every minute of it.
