I think it's a great job, but you also need to be lucky and hard working
Reflecting on my career I had to de more of the latter than the former. However, I was lucky in that my hard work paid off and a life of nomadic adventure ensued.
For the cadet, who is thinking of embarking on an expensive educational leap of faith, I would suggest the risk of being lucky is huge. Hard work might not cut it. (I know of people who are still out of work, can't get an interview 4 years out of flight school. Indeed, that delay is acting against them). The debt will still be hanging there and you wonder why did you do it.
If you can by-pass the luck with a sponsored scheme I'd probably give it a go and employ hard work to advance myself. If you encounter base luck it will be a very expensive mistake.
