Aye and there's the rub......
There are countless people in all walks of business who have reached some elevated status through various blends of ability, skill, tenacity, business acumen, luck and sheer hard graft.
In my experience, someone offering a good, reliable product to the right customers at the right place and at the right time will win hands down over a brilliant concept being marketed by someone with no idea of how to deliver it or how to promote it or themselves.
