A lot of things in life are a gamble and training to be a pilot seems to be one of them but if you dont take them chances you may never get where you want to be.
I've said this a number of times before; there is a huge difference between a gamble and a calculated gamble or risk and calculated risk as I like to put it.
You'll never find an entrepreneur taking a risk without weighing up the chances of success and failure even though they are spending a considerably less amount of money.
Look at what's happening in the market, (news headline this morning that the UK is already in recession) and weigh up your chances of getting that dream job. You may think it's worth the risk and if you do, go for it however if your head is giving you warning signs; maybe it's something you should be listening to.
