Education? Experience?

I'm really bad for not taking an opportunity and seizing it when I can.  I'd rather sit back and watch the next guy go further, succeed and do better than myself. 
I have no idea why I feel this way either.  And when I say feel, I'm not even to sure if I feel anything but guilt.  I'm ok with where I'm at in my life.
I often feel like I should be out there helping people in some way, like my purpose here is greater than what I'm doing; and that feeling comes and goes, but mostly comes these days. 
 
For the last couple years I've been a taxi driver in a small city and I love doing this.  I get to meet all sorts of people but mostly I get to see raw human emotion and that in it's self can be very interesting.   
I've seen a jealous girlfriend freakin' on her boyfriend for lookin' at some girl;  I've helped a drunk lady crying, trying to find her way home;  transported a child scared because Mom wasn't home to let her in after school.  
My job allows me to see people sometimes in their most vulnerable state.
Do I dare give them advice, suggest or even try and tell anyone to do anything?  I dare not!  I'm just a taxi driver. 

I was once told that just sharing my personal experience was advice and that little extra push to do better.
I wasn't sure if I was suppose to feel happy or violated.  I wasn't giving advice, but somebody took it. 
After thinking about it way to long, I concluded I should just be happy for that person.  I took many things in my life, including the idea on sharing experience, strength & hope. 


Now with starting this note today, I thought about the purpose, my purpose.  Do I take an opportunity to get back into school and become a helper of the community, or do I stay at the current job I love, driving taxi cab?
 
I know no one can answer this but me, but today, I'm not even sure if I can answer it. 

Ya, ya, ya, I've done that too...dropped to my knees and asked what my purpose is and why am I feeling guilty for enjoying the job I'm at.  I still have yet to get a response.  Is this one of those things that will come to me in time?

Bah, anyways, this has been the heaviest of my thoughts these last weeks.  I'm feeling guilty for liking my job and not doing something more.....see I can't even put a word to it.  (I'll argue this in my head now for a couple more hours LOL)  Well, as long as I'm writing it down and sharing it....I know eventually, YES, eventually it will come to me and then and only then will I know what my purpose is.
