so im in high school and next summer im planning on starting a small computer repair business for extra money on the side, no storefront, not too much advertising, nothing big at all. ive done my research in running a business and im fairly sure ill be able to take on most jobs that involve common issues, but i would like to know from people who have experience- is there anything i need to watch out for? /is there anything you think i need to be aware of? and please feel free to tell experiences, anything helps.
