I am tempted to say, if it ain't broke, don't fix it.
Some things that might be appropriate to personal development:
A part time job.
A single college level course to try it out.
Mentoring by a college professor.
Just a couple ideas. It sounds like you have done a great job thus far.

I'd like to add....
Volunteer work
My son is volunteering at a place that works with kids with life threatening illnesses. The work he does isn't medical in nature. But the experiences he is having has been wonderful for his development into a capable, caring, compassionate, young man.
Internship...we are looking for a lawyer for my younger son to either mentor or allow him to intern at his law firm or hopefully both. He is still young so we are waiting until next year.
