TITLE: What to do with a LARGE amount of extra income?
POST: I've read the guide on saving that goes through all of the steps, aka "I have $X, what should I do with it?" But I'm now all the way down to step 5 and 6, and I still have a LOT of money left over.

My situation is a bit odd: I'm just barely 21, graduated college with zero debt on scholarship, and have a tech job that pays over 100k a year. My car is paid for in full from my high school through college days, and pretty much the only recurring monthly payments I have are rent+auto insurance+utilities, which add up to a bit less than $2k a month. I tend to eat as much at the company for lunch as possible, and cook for myself at home for dinner so I probably only spend $100-200 on food a month.

This leaves me with a very significant chunk of money from my paycheck that literally just goes straight to a bank account right now, gathering dust. What should I do with this?
TL;DR: 
I have a lot of extra income, I'm young, and I don't know what the best use for it is.
