I attended a conference of CEOs and Consultants earlier in the month and found it very motivating. The speakers shared a lot of their knowledge and explained what attributed to their success. One of my favorite was probably also the most simple; Comparing work ethic to a vending machine.
When you want to buy a soda from a vending machine, it usually costs $1.00. Sometimes even more, which I don't understand! Regardless, if you put in 50 cents, you don't receive half a pint of soda. If you put in 99 cents, a cup doesn't pop down with 99% of the soda in it. In order to get what you want, you need to put in the whole dollar.
Putting in half the work, or even most of the work, doesn't get you anything. You can put in half the work at first, but you're only delaying the time for you to get your ultimate goal. You won't get your reward with anything less than 100%! For me, being an entrepreneur was my soda. This is a business where it's not for everyone. Not everyone is willing to put in that whole dollar to get what they want.
