Last week I asked the question, more for myself after a 'complaint' by my partner when enough is enough in regards to reading books, blogs etc on growing the business as well growing as an individual.
Comment made by my mentor on this 'issue':
"Remember, "Success is the journey", not the destination - you never stop. Like anything in life you move on just a little more each day. We all do - even I keep reading, attending seminars, talking, etc etc!
I will never know everything - how boring is that?"
Well for one thing, he's never boring.
Read another wonderful quote on this only yesterday (because I will keep reading of course):
"It's more important to know some of the questions than all the answers" (James Thurber)
Learned something again, just by reading
(Side-note: last sentence could be entered in the Keep it Brief contest!)
