FFXIV is designed for party gameplay not solo, so playing solo more or less will drive you to quit this game after awhile. At least that is how it is for most ppl.

As Rau said get a linkshell, try to find one that is active. Once you get that you will be able to get partys, help leveling up, and everything else.

Xp will come about 10 fold faster, leveling will be less boring, you will have access to do different events outside solo grind.

It is a different game once you start partying with other ppl.
