we have to deal with a hard and essential fact: we discover that the things we're good at and the things we love are not necessarily the same...(wisdom from Robert James Waller)
and we must never feel guilty about it or distressed by this realization.
.........I may be very good as a teacher, but my heart may lie with wanting to run a cafe cum library...
so I do what I'm good at and dream about the other....knowing that it's all right to do so....
By extension this fits into so many areas of life....
