EVE General Discussion

In a nutshell OP, every ship in EVE has it's own role it excels in.

DON'T cross train in the beginning, you will just be wasting time and SP. Stick with Gallente since you seem to have invested the most SP into it.
Look at killboards (Zkillboard) on losses of the ship you're currently flying to get an idea how people fit them. I would suggest starting with T1 frigates because they're cheap to lose and a cheap way to learn game mechanics. Learn how most ships you encounter are fitted and pick fights where you have a chance of winning. For example if you decide to fly an afterburner Incursus, then avoid things like Condors and Slicers. (Use the directional scanner to get an idea of what's in space before you warp to it).

This guy >> LINK << has some pretty good videos for newbros and that video gives you a pretty good overview.

In conclusion, get into cheap frigates, learn the game (mechanics), learn how to fly your ship and pick fights, and don't be afraid to create hilarious loss mails. Best thing would probably be joining an active pvp corp where you can fly in small gangs and learn from your corp mates.
