Now this is a REALLY tough question to answer.

That is because, you haven't stated as to how much money you've got, and what are your educational qualifications, and from where did you get them.

Case 1:

If you've got a REALLY BIG LOAD of money in your bank accounts, well then, no hassle. Buy a good showroom anywhere in a popular market, and you can then lease it to any person/organization. The best and hassle free lessees are banks. They pay via a money transfer in your account, and they deduct the taxes automatically.

Please note, investment here could be anything above US$ 150,000 (At least that's the scenario where I live!).

You could also buy agricultural land anywhere in the county side, and lease that too!

Case 2:

If you have money, but not the amount that stinks, you should probably open a nice restaurant. Even here, a really nice investment is required, and that too a smart one.

For example, you should open an eating joint that serves a unique cuisine. Like Indian, or Thai, or Egyptian! That will attract people fast, and it will bring in good returns as well.

With the eating joint, you can open something like an arcade too, a place that has bowling, snooker, etc. But you'll need to do it on another floor of the building. Which might increase your expenditure as rent per floor can get expensive at times.

Starting a business is a REALLY brainy job. You need to be smart, intelligent, and need to have full knowledge about the type of business you're gonna start. Be it an eating joint, an amusement park, a nightclub, or even if you take a franchise of anything. It can be stressing at times.

Investment here could be anything more than at least half of what is required in Case 1.

Case 3:

If you're talking about a government job, depends on the type of job. If you're saying that you want to go into IR. Then of course you'll get what you want, but that will come in after a lotta hard work. International Relations is tough, and it is advised to those who have an interest in History, and Political Sciences, and to those who have good MUNing experience, as the United Nations, or even Embassy work could be really boring if you don't have an interest there. Though, the pay is good.

If you're saying you wanna join the police force, and work your way up into the NSA, etc. Well then, prepare to live a life of patience and hell. Reaching to a James Bond style position will require at least a LOT of experience, or requires you to be REALLY good, and the type of person who makes a good impression to your seniors; that too fast.

Investment here, depends, and is variable and unpredictable.

Case 4:

If you're a person whose higher education is still to come.

Then I'll advise you to give your SAT, then the LSAT, and get into Harvard Law. Graduate with a JD degree, and work your way in Boston to get some experience. Then, get into Harvard Business.

Of course, you can always choose the stream you want, like Harvard Medical, or Princeton or MIT.

Any Ivy league college will get you a excellent pay package after you graduate. Enough that if you live like a miser for about 12-15 years, you can retire later, by following Case 1.

Investment here, will depend on your score, and on the type of college you go to.

If the college offers 100% scholarship, and you want that, well then your SAT score is expected to be MINIMUM 2275 out of a possible 2400. Along with other outstanding/unique additions on your resume. Something off the page/out of the box.

If you're looking at a college like Stanford that doesn't give any scholarship/aid. Well then, you should be ready to shell out anything near US$45000 per year. Along with an AMAZING SAT score.

I just read the additional detail that you added.

Master's In Financial Management. Hmmmmm. That seems interesting, but isn't the degree Master of Accounting & Financial Management(MAFM)?!

But that's a bit irrelevant now. You can become a Charted Accountant for anyone(that is if, you've done CAship!).

CA's earn a really good package by working for rich people(but that comes a after about 10-15 years of work experience). In the beginning, a CA earns approximately about US$ 1500-2000.

If, however, Accounting is not your game, you could start with trading at the Wall Street.

I play this game, The Wall Street Survivor. It's really good for practice. And you win free gifts too!

You can start practicing your skills in trading by Signing Up at http://www.wallstreetsurvivor.com/

And when you'll be able to predict stock movements with maximum accuracy, you can start trading in reality! :)

I hope my answer helps you, and wish you the very best of luck with your future. May you get success like Warren Buffet, and lead on to live a happy life. :)

PS -- Don't mind the capitals. I mean to emphasise on those words/phrases. Not to shout at you. :)

Study hard and if you don't have any interests but money, study to get to Wall St.

If you have interests, study to get good and the money will usually follow.

Study banking or jewelry (something like gemologist)
