Art! Any/every kind! Pant,oil, drawing. Music, song writing, an instrument. Or creating something with your 2 hands! Like knitting, sewing. Even write a book. I'm 14 now(my birthday was last week) and I do all of the above!! And I have 3 siblings and in 9th grade(no homeschool). I no knitting?! I'm like half way thru my first scarf!! Its not that bad.
My daughter was Home Schooled from 4 Th Grade on. She did Cheerleading for the City, Martial Arts, Youth Trips, Classes at the museum and the local Zoo, Dance learned drums, language on line, arts and crafts. She was very busy and very social. You can make it fun
