need advice as a 18f looking for a career in finance

hey guys, im currently an undergrad student in quantitative finance and economics in one of my country's national institutes but as someone from a relatively weaker economic section, ive never actually invested or traded in markets (close to zero real world exposure). while i love to work with data, statistics and calculus, im feeling increasingly skeptical about going into quant. will it be too draining? will i even get in? will i be able to keep up? can i still pursue my side hustles (im kinda a graphic designer too)?
i wanna speak to a professional who's already in the field/anyone with any experience. pls come forward or help me connect with people if you know any.
