I am serving you a menu of quotes (just sent into my box) and compiled by the memory and sales training expert. Ron White.
"There are those of us who are always about to live. We are waiting until things change, until there is more time, until we are less tired, until we get a promotion, until we settle down -- until, until, until. It always seems as if there is some major event that must occur in our lives before we begin living."
-- George Sheehan
"For all sad words of tongue and pen, the saddest are these, 'It might have been'."
-- John Greenleaf Whittier
"Now is the only time there is. Make your now wow, your minutes miracles, and your days pay. Your life will have been magnificently lived and invested, and when you die you will have made a difference."
-- Mark Victor Hansen
"Handle challenges fast. If someone has a challenge with your product or service, take care of it right now."
-- Tom Hopkins
"Stop rationalizing, stop stewing. Get up out of your chair and start doing."
-- Denis Waitley
"It's a strange thing, you have said it thousands of times I am sure… you will never know what you can do until you try. However the sad truth is, that most people never try anything until they know they can do it."
-- Bob Proctor
