become a flight attendant

Im not sure how to add a comment to what other people say…can u help me out?

I am 17, turning 18 in a less than a month. The minimum age to be a flight attendant for Air Canada is 18. I am going to a hiring fair in 2 weeks; they are hiring staff to begin in the sumemr. I have the required 2 years customer service experience from working at Tim Hortons and I have had great reviews. My uncle has been a flight attendant for 17 years and he loves it and he recommended that I apply. Do you think that I have a change at the job or am I dreaming. Should I read that book that everyone is talking about?
