Congrats! You are doing fantastic. Thousands of debbie downers here, pay absolutely no attention to them. Keep doing what you like, strengthen yourself physically and mentally and if you need to have a second job while you get your first break-away success so be it.

Just a small correction, "Yerba mate" is not the "coffee of south-america" Coffee is the coffee of south america,i.e. by far is a more popular drink. Mate is huge in Argentina/Uruguay and perhaps Paraguay , only regionally in Brazil and very niche everywhere else in the region. Coffee is as popular as it can be everywhere else in the world where the drink is liked.
