just to get the facts straight: Four years of failure is basically nothing. If you are looking at a prop shop, out of 100 hirings about 50 leave after 6 months, further 30 don't survive the first year, 10 leave after the second year and from the 10 remaining about 2 are making serious money after 3 years.
That said, prop shops have training and mentorship, now imagine how the failure rates are for people who start without guidance.
On another note, there are also fields in this business that don't require P/L responsibility, like execution trading. You're so young that you would not have any issues to land a job in sales trading or as an analyst, HOWEVER, you have to bring something to the table.
Don't expect anyone to give you a job just because you are nice. Study, get good grades, do interns, network. Competition is extremely fierce and you have to compete
