Whether it be a group or just a friend, you must maintain a weekly tie with someone who's not afraid to ask you how your walk with Jesus is going. I know an accountability person may cramp your style as you climb the ladder of personal fortune and worldwide fame, but this world has a way of turning us gung-ho Christian folk into complete jerks if we lose sight of the Saviour. All the world has stages - Not quite the Shakespeare line, but all the world does have them. And you need to find them, and perform on them - wherever, whenever, and for whomever you can. Don't ever be afraid of experience.
Experience is sometimes bitter, sometimes sweet, but always nutritious.
I think stage time is more valuable than the money you make. So look at every opportunity as another step closer to reaching your comedy goals. Find your own voice - We all have our influences. And don't kid yourself into thinking these influences won't spill over and provide some of the essence of your act. Still, it's important for you to find out where your strengths lie, and find your own voice.
