Great advice in the answers above.

The big thing to me in all of this is to communicate with others in your FC.

Players sometimes join a Free Company, but do not communicate unless someone else directs a question specifically at them. This can become an issue when after weeks or months a player hasn't moved beyond that stage. Because there is little communication with them, it's not clear what advice they need or want to do; without them asking for help, no one really even knows that they need it. Later on such players can become annoyed and disillusioned with the experience, all because they did not communicate with others.

So, please, communicate. Talk, chat, ask for help, ask for advice, offer your own help to others whenever you can. Become part of that FC community. I think you will find it very helpful as you play FFXIV.
