Tim, It's all about discernment. What is it you are called to do? Mike's points are well taken, and I mostly understand them, however, there ARE some things one can't do as a free-floating lay person. Like preside at the Eucharist. Like hear confessions and grant absolution. Like devote all your professional/vocational energy to a parish. If you are called to these things, or think you might be, get the into spiritual direction of some useful format and into a discernment program that won't preclude any options.
