It's hard to give advice to young people, because the world you're forced to grow up in is night-and-day different from that which most of us came up in. You all have it way, way harder.

I think the best advice I can give is that waiting is only going to compound the problem. I remember being your age and going through several jobs over my late teens and early twenties. It's a process, and some of them you're going to hate, but you will learn about yourself in the process and hopefully earn some money.

Also if your parents are housing you freely, you need to be doing something to help them out, assuming you're not already. Figure out which chores they hate the most and make a habit of doing those for them. It's just a nice way to repay them because they're doing more for you right now than may be apparent until later in life.

One last thing, whatever you decide to do for work, always put something aside for your retirement. A dollar you put in an investment account now can turn into 100 by the time you retire, and that is particularly true for a nineteen year-old kid. You can set one up on Robin Hood and put a couple of bucks per check in VTI or a Vanguard index fund or an ETF and just forget about it. You'll thank me in 40 years.
