Most importantly is all of the good friends I've made. If it wasn't for them I would likely have quit a long time before now.
Then there are other things such as taking my first few steps into RP, before Aquilonia I had never RPed before. Server firsts with LPTC raid alliance and some of the fun moments we've had on vent. Someone taking the time to try to teach me how to PvP on my level 80 sin, but then proceeding to slaughter me repeatedly with his level 40-50 sin (I think it was that low, was a good while back now)...
