As a high schooler, what difference does it make how I spend my money now?

It is important to start saving at an early age. You can set some financial goals for things that you want to buy in the future instead of spending it all at one time. You can save for bigger ticket items, like a car.

Explanation:

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
