To be honest, I felt just like you and I spent a year working a boring job and nearly went insane. I ended up forgetting about getting ahead in life, and since I wanted to travel, I put on a backpack, took my $500 and headed to mexico for an adveture. I was able to spend 5 months there, then I had to come back, work a job for a month, I managed to save $1000 and then off I went again to another third world country where I could live for a while, I managed to make that last about 8 months (after the plane fare took a big chunk). Then I came back, worked a boring job for about 2 months and saved up $1700, and that bought me more time to be a free wanderer.
That was what I did when I was 19, I discovered that you can live cheaper if you traveled in third world countries with your backpack, didn't mind roughing it a little, and it gives you lots of time to find out who you are, what you really want in life, and gives you some worldly wisdom. I encourage you to forget about getting ahead for now and just be a free wanderer until you know what you are really meant to do. Don't waste your money going to school until you know what you're really meant to do.
I enjoyed Christine Breese's talks on youtube about this kind of thing, and I also enjoyed the course on Life Pupose at Unversity of Metaphysical Sciences at
