My life is so........?

I'm in a similar situation. I graduated from High school when i was 17. I am 19 now and have yet to enter college for lack of money. I am working right now at a department store, having to deal with rude people who lack manners. Being in this situation has made me want to work harder and earn the money to be able to attend a college so i won't be stuck in this job for life, like many do. I also do the same like envisioning what my future life will be like. My only advise is to not give up and use every resource you can to make it to college, good luck.
