I am a working professional and I also experienced difficult time and was a late bloomer. Because I feel your hardship, I spent 15-20 mins of my valuable time to help you make a difference in your life. I wrote all these suggestions because I see a possibility in you. Based on what you indicated, there’s a possibility of getting into a good school and reset your life. Ivy leagues can be a possibility. Like the I-banker said down below, your 10 years of hardship must have taught you something. Leverage that to turn things around to something very positive. Hope my comments and Ibanker’s comments below will help you. And try to get over with your pessimism and daydreaming, which seem to be the common problem of your generation in Korea. You want to work in Wallstreet but you seem to have a zero understanding on what it takes to be a wall street professional or even livew in Manhattan. Because of that, it just sounds like you just want be a someone everybody in Korea will look up to but did not bother to take time to actually understand the career you want to have, which makes you sound naive and lazy. Again, you have a potential to become a better person. However, your time is running out. Hope you not waste the advice from me and the I-bank below. Some people do pay few hundreds just to get this kind of advice.
