1. continue to do leves and behests until you get to around level 20, you don't really make any real money until then. just remember to save it all up and don't lash out on anything to pricey at the markets as prices are never constant and you can often find some gear pretty cheap.

2. During behests, if you find someone that speaks English you can usually get into a convo with them and share some leves etc. I only really started making proper parties in the mid 20s. Also spend some time on your servers forums and ask around for a linkshell, once you're in a linkshell you're set.

3. I know its hard with no real goal in mind at the moment but keep at it. If you are playing alone and doing the same thing over and over again you don't feel like you're getting anywhere. believe me, once you have made some friends it will be fine and everything gets a whole lot better!
