My favorite quote on pride (which I heard on Our Life In Christ): "The sun shines on all alike, and vainglory beams on all activities. For instance I am vainglorious when I fast, and when I relax the fast to be unnoticed, I am again vainglorious by my prudence. When I am well dressed, I am quite overcome by vainglory. When I put on poor clothes, I am vainglorious again. When I talk I am defeated and when I am silent I am again defeated by it. However I throw this prickly pear, a spike stands upright." - St. John Climacus
Getting back to homeschooling - I skimmed through the article posted by Antonios - the first one. The author recommends ... etc. I hope this is slightly helpful.
