I changed jobs from highly paid, owning a couple of helicopters to lowly paid flying for a living.
Best piece of advice anyone gave me was stay in the day job and fly for fun.
I ignored him and continue to do so, however if you change jobs be prepared to make little or no money compared to what you do now.
Yes it's fun, but be prepared to deal with some complete muppets and maybe even work for them!
I love what I do in the helicopter world, still have to dabble in the old job every now and again to pay the bills.
Forgive my cynicism, I am not trying to put you off your dream, just point out that if the money is good elsewhere, that sometimes you can do worse than grin and bear it. What about part-time half trading / half flying.
