An interesting thought you give here.
You think, that by me telling people not to cast spells just because they're bored in piano class will cause people to stop using magic all together as they'll get lazy... I find this opinion out of proportion and quite amusing.
If you find it necessary to cast spells just because you're bored that's your business. And if you need to cast spells as often as you get bored just so you have the motivation to cast at all, is your business.
But I'm pretty sure if people held more respect for how things naturally are instead of casting spells for cheap entertainment, that magic will not dissipate as you seem to believe.
Now, if you were trying to argue for the simple pleasure of arguing, I believe you got my point wrong. I'm not telling "newbies" not to cast spells, I'm telling them not to cast spells just because they're bored.
Thank you for the input though, I found it quite interesting,
