Assuming that I’m in a position where even fast food chains won’t hire me (and believe me, these guys will hire anyone), beg for spare change; get enough to buy packed water and start selling it on public spots. This should get me enough to feed myself and save up a little. Sleep in parks. Use gyms to shower.

After I can reasonably do my hygiene too, try to apply jobs within my local range. Newspaper job listings could also help a lot here. There always exists some need for a job in somewhere after all. I’d be guaranteed a minimum wage (which is not a lot in my country), but definetly would let me afford rent and food. This is a satisfactory end for some people already, but to get bigger you can try to find work in smaller political parties next to get connections (sometimes people that rake in lot of money could have the dumbest political ideas); or save up to get a small motorbike to open up your job opportunities even further.
