<prompt> Human: I just turned 18 last week. Im graduating from high school at the end of this year and I pretty much already know what I want from life. I tried the MASH lifestyle calculator and it said I needed to make 200,000 a year to maintain my lifestyle and that doesnt sound right to me. Sorry if my writing is shitty, Im pretty bad at it. Im going to divide this up into sections and hopefully someone can give me some advice.Education: I want a masters degree or possibly a PhD or an MD if needed. Ive taken enough college classes and APs to put me into my junior year when I start I think. Im fairly sure Im going to Georgia Tech for my undergraduate because they are required to take my credits and it will cost me about 10,000 a year about 5 will have to be loans. I have no idea where I will go for my masters or higher but it will be somewhere equal to or greater than Georgia Tech in prestige assuming I continue on the same path. Im majoring in applied mathematics at the moment but Im definitely open to that changing. Im 99.9 sure Ill end up in a STEM major.Career: I love math and its most likely where Ill end up but Im not entirely sure what I can do with a math degree. I also love computer science and Im like 13 of the way to a minor in it so I might go for it. I would also consider engineering or medicine probably not this one though. Im also open to applying a math degree to finance or something. I need something that will give me enough money to live the live I want. I also want a career thats has a lot of freedom for travel.Lifestyle: I want a small apartment in a fun city NYC, San Francisco, Boston, London, Paris, etc. but I want it to be a nice apartment. One bedroomstudio would be fine. Ill probably take public transportation everywhere. I dont want kids. This may change in the future but at the very least not until my late 30s. I want to pay for quality but I dont want a ton of shit that will just weigh me down. I want to travel frequently for long periods of time and I want to do it while Im young. When I say travel I dont mean flying to five star resorts in the Bahamas, more like backpacking but paying a little bit more so I can enjoy myself with frequent nights out, etc. When Im at home Ill frequently go out and do stuff like bars, up scale restaurants, etc. I think my parents have retirement covered but if they dont I will have to help them.I dont really know what else to say. Im mainly looking for advice about whether Im delusional about my future or not. I dont know what to do for a career and I dont know how much my lifestyle will cost to maintain. Any advice would be appreciated though because I know absolutely nothing about personal finance. Thanks in advance for any responses!  <response>: So you want to live in one of the most expensive cities in the world, want to travel frequently for long periods of time, go out frequently the time including upscale restaurants dont forget, already in some of the most expensive cities in the world, and possibly help support your parents? 200k doesnt sound that high to me.The travel frequently for long periods of time is what makes this infeasible unless you freelance and can just stop working when you feel like it.
