<prompt> Human: 19 years old. Just started a job making 55k a year just over 40k gross. 25,000 company stock options vested over four years. No loans whatsoever college, car, house.Other things to note: Monthly expenditures come out to roughly 1200month 750 - rent w utilities, 400 - healthy groceriesoccasional eating out, 50 - cellphone Roughly 400month to visit and hangout with out-of-state girlfriend Payday is monthly 1st of the month Dont need a car where I live because I can walk to work, but am considering getting one to make it easier to explore the city and travel to nearby big cities. Wouldnt spend more than 5k on it. Company I joined is a startup, but is growing REALLY fast and has already made a substantial amount of profit in a relatively new industry. If i stay until all my stock options have vested, those stock options will possibly be worth 1 mil if not much more based on research of comparable public companies in the market. I know all this is still a big if. I have practically no savingsinvestments currently. I was fortunate enough to be in the right place at the right time with the right skills. Im actually still kind of in disbelief at it all.With that said, since I am only 19, I dont have much experience savingbudgetinginvestingetc. What are some things youd recommend I do to keep on financial track? Any best practices? And I am interested in investing and growing the money I make, but I have to admit Im a little intimidated by it all and lost as to where to start. Shedding some light on the subject would be appreciated. And whats the best way to establish some credit? I currently have a credit score of 0 because I havent done anything to establish or ruin credit.Thanks in advance!And yes I am using a throwaway for privacy sake. Im also purposefully being vague about the companyindustryareaetc. You can probably understand why  <response>: This extremely unique situation sounds like every college dropoutgraduate that just got a software development job in the Silicon Valley, but theyre getting paid more.
