Worry for Devon

Devon is doing great this school year, but I worry that he has taken on, or should I say won't let go of some things.  Devon is still active in his Venture Crew, still active in Beta Club, still working one day a week (on the weekend), taking a rigorous course load at school and running cross country for the school.  He did all of this last year at this time except for that he didn't have a job.  I thought that might have been too much then, now we've added the job and the stress of learning to drive. 

Devon doesn't want to quit his job or cross country, or Venture or Beta. 

I guess as long as he feels he can handle it, I have to trust him...a mother's worry!
