13yrs in the industry. Grew up around american IFR offshore pilots so had VERY skewed expectations when I got my license and started out in the Canadian industry.
Be prepared to give 100% into the industry or don't even try. Have a backup plan and learn to live with extreme frugality for the first few years. Very few guys that get their license ever make a career of it. If you're ambitious and have a good work ethic you can make a great life of it. I'm currently loving life in mediums, working for a company that keeps me as busy as I want to be. I've flown in Africa, Europe, across the US, Canada, and the ugly side of the Caribbean. I'm had beers with high ranking political figures, TV and Movie stars, been shot at, arrested, hospitalized more then once. It's been a fantastic ride, but not without it's sacrifices. You'll work with amazing people, at both ends of the scale. You'll burn through friends and lovers at a pace thar usually mirrors your long shifts away. You'll miss birthday's, furnerals, and many other events people consider significant. It gets better the longer you're in, but the first few years are rough.
Visit helicopter companies, talk to pilots and engineers. Believe nothing you read on the internet or are told by flight schools.
