A chap I know, from a highly privileged background, took up flying as a hobby....
Looking for challenges led him to an IMC and Night ratings.......he decided to try for a Commercial licence, not because he wanted to fly shiny jets, but simply to improve himself.
AFAIK, the school concerned was North Lincoln/Southeast Yorkshire based, They boasted a very high success rate.
SIMPLY BECAUSE PROSPECTIVE CUSTOMERS WERE RIGOROUSLY SELECTED ON ABILITY TO PERFORM.
Needless to say, he qualified. He was adamant that all the cash in the world would not have bought a place on that course....(OTOH, if you couldn't raise the finance, you couldn't join.)
Like him, all students should do their research and weed out the the sausage-machine enterprises who'se driving criteria is "can you pay"
Yes, he wound up instructing to build hours. also did pleasure-flights for a bit of fun and aerial photography. To that particular person,commercial flying is just a sideline. He used to keep a tail-dragger to play in. a good, safe Pilot,who has natural ability.
