Dream Job?

Right now, I have a friend that is in a job that is not worth her.  She dreams of going to college, of getting her nursing degree, of having a job that means something to her.  I totally get that.  Not the college part or the nursing part, but the meaningful job part.  That ship has sailed for me, which is fine.  I can keep at this gig, it pays the bills and I don't hate it.  But my friend, she is young and huge hearted and can be something more.
I now live vicariously through others.
She is talking about taking some test to get some certificate.  Anyway, she is excited.  I am excited for her.  It's not that I want her to leave me at the work place, it's that I want her to follow her dreams.  It is fun and exciting to see her get excited.
I, on the other hand, have no employment dreams.  That's ok, isn't it?  Seriously, couldn't I just settle for this job and let it pay the bills while I enjoy my homelife?  I am doing that right now and it seems to be working out for me pretty well.  I wish I could have stayed with the hardware company.  I wish that the fitness place could have turned out somewhat differently.  I wish I had a marketable talent.  I wish the people at corporate never monkeyed with a good thing.  But I couldn't, it didn't, I don't, and they did.
Another person at work has just announced his retirement.  He has been with this company for fifteen years.  This was his post retirement job, he is 80.  He has decided that he wants to do some traveling and a few other things while he still has the time and the job has lost some of it's shine, he says.  He doesn't have to work, he wanted to.  I won't be like that.  I understand the desire to be busy, but I don't think I would want to be scheduled for busy when I don't have to be.
It is ok if I don't love my job.  It is ok if I stand back and encourage everyone else around me to chase their dream.  My job dream isn't out there.  Not now, not here. 
What is my dream job?  Well, for a long time it was to be a tour guide in Rothenburg.  I always enjoyed the enthusiasm and never ending facts that flowed from the flag/umbrella carrying tour guides. 
What other dream job?  Finding something that I am good at.  My job now, I am good at half of it.  That is hard for me because I was always good at all of it. 
So if anyone knows of an opening for tour guides in the Des Moines area, please let me know.
