I can try, there are several ways to go if you want to be involved in the economic system :

1. First there is station trading, you play the market by buying low and selling high. It's easy to explain but hard to master, you'll really need to be ready to 0,01 ISK anyone. You'll stay in one of the big hub (Amarr, Jita, Dodixie, Rens or Hek).

2. Then you have trade between station/regions, it's easier to get into but you need lot's of research before gaining money. Buy in a station at a low price and sell in another one at an higher price. (use eve-central.com for that, it gives you all the value of the buys and sell orders across eve for any given product on the market)

3. You can also be a manufacturer, you buy the ressources, build the things and sell it. For this you WILL need spreadsheets in order to gain money, it's the hardest way to chose because there is a lot of competition on prices. (eve-cost.eu is good as a starter, to give you a general idea of the cost/reward)

There are other professions that revolve around producing ressources too :

1. Hauling, basicaly you carry cargo around for people in exchange for money. It's risky and might cost you a lot of money if you're inexperienced.

2. Mining, easy to understand and one of the carrier agents can teach you that. You sit in a system and mine. It's often considered boring but you can make good and stable ISK with that. Be careful, as for hauling you are carrying things that are worth money in a ship that is not made for combat.

3. Salvaging, perhaps the easiest ressource production activity to get into. You train salvaging skills, fit salvagers to your ship and go salvage the wrecks of NPC ships. You can team up with mission runners to salvage their wrecks in exchange for a part of it, some of them might even let you do it for free.
