this is what i love to do. follow your passion, i think that's your best shot at being happy. if, after 10 years, you hate what you're doing, do something else!!
still, the question is a little silly. do we have regrets over what has actually happened in our careers versus what we imagine might have happened if we'd become doctors, lawyers, professional athletes? sure. do we have a realistic view of those other careers? i doubt it.
Doctors - every friend of mine in medicine has close to $200k in debt after 8-10 years of training. some are lined up for lucrative tracks - radiology, dermatology - some aren't. they work lots of weekends/holidays/graveyard shifts when they're getting started. some will make hundreds of thousands a year, most will probably make $60,000 - $80,000. with managed care, most salaries have dropped at least 30%. you think aviation is a messed up industry? what, like health care is some beacon of efficiency and aptitude? and hey, if your landing doesn't come out quite the way you planned, at least you don't get sued to have your license taken away...
Lawyers - also takes many years/$$$ to become one. Average salary? less than $40k/year. still, i know a guy who got on with a prestigious firm in Chicago. makes close to $100k after 3 years with the firm. works at least 80/hours a week. only goes out with people from work - has no time to meet anyone else. gained 30 pounds in last two years, doesn't have time/energy to work out. desperately wants to find someone and get married but is depressed about rate of divorce among colleagues. wants to transfer to smaller city/smaller firm but can't afford it until loans are paid off in 15 years. works mostly for big corporations defending their more than questionable actions.
i can tell you about others who are doing great, really living the dream, but we're focusing on regrets. so why do some stay with it? it's in their blood, they don't know how to do anything else, they don't want to do anything else, they're too afraid to do anything else? depends on the person.
you want to work 9 to 5? there are jobs out there. Want to spend more time with the family? ok, then do it. What's stopping you? You think your kid really cares if you're a pilot vs. a garbageman? more likely, it's you that cares more.
every year or so i'll find an article about a school janitor who leaves $2 million to the school district after he passes away. usually the guy worked there most of his life, lived simply, invested what he earned, sent his kids off to colleges he could never afford, then gave back to the place where he saw so many dreams, so much potential.
Choices, choices, choices. all you have to do is make them.
