its wide consense that there are two kinds of eve players: these that play to get ritch, and these that play to blow up stuff.
but of cause. no matter what you do, you will need some income.
i agree to the advice to stay away from industry. players that have etablisched productions will dictate the price. at best you will be able to make a tini profit, but that still will be a loss for you, as you could spend your time on stuff that makes much more profit.
same goes for mining. its a waste of time and income. most minerals actually dont come from mining but reprocessing mission rat drops, these that do mine usually do it on a second account while their main character does low attention stuff, and finally, mining will always make you a target as many players love to kill miners for funs and giggles.
factional warfare will be rather borring with low skills. but it will make great isk (as in GREAT compared to anything else you can do with virtually no skills) and teach you how to survive in low.
another popular way to make an income is to run security missions in highsec. for the first 2-4 weeks your income will be very low, but it will get better after that.
still, grinding in enough income to pay for your subscription and the stuff you want to buy will be rather difficult wich missioning alone untill you have at last half a year of skill training.
finally, you can do some planetay interaction. but lucrative places to do this are scarse in highsec, its dangerous in lowsec, and molas can tell you a story about how it proably would work out for you in sovspace null.
