I would say to these "I WANT" people that I am too busy to
do it myself, but would be thrilled to teach THEM to do it.
They may surprise you and actually want to, but my bet is that
they won't want to bother with it.
Do only what YOU want to do, for whomever YOU want to do
it for. This hobby takes far too much time and money to do it
for everyone who simply "WANTS".
