When I think back to my school days, it just feels like a huge waste of time.
Sure, we've been taught a ton of things during that time, but imagine how much more you could have learnt with the right support... with someone who would actually listen to _your_ questions, instead of just going through the subject materials? What if someone actually fostered your personal interests and talents?
Of course that wouldn't scale, but with kids being so eager for knowledge, it just feels like lost time.
