Don't get discouraged. Conceiving, planning, and running a good event is hard. If it is something that you are passionate about doing, keep trying. Take your time to think of as many details as possible. Read thru the settings in the Players Guide (three or four times if you want...there is no rush). Try to think of something a bit original that fits the settings as well as something that your character would be involved it. The details are what really brings the event to life tho. Also, some of the best events happen after some time of building up in the background. Rather than something that just 'happens' suddenly for no apparent reason, try thinking of smaller occurences that build up to it.
Hope these thoughts help. Good luck.
