I've met a lot of really successful entrepreneurs.
I've noticed that one trait they all share is a great hunger to create more, achieve more and get better.
But as you become more successful, hunger can give way to comfort, satisfaction and a slow and almost imperceptible lowering of standards.
Sometimes the fastest way to grow your business is not to add anything new.
But rather to strip away the old.
Old tactics. Old products. Old ways of thinking.
If you are frustrated with how fast your business is growing, take a look at how you are using your mind.
Have a think about how you think.
Specifically, examine your self image - and whether it is putting a limit to the level of success you are reaching.
Today it was announced that Jeff Bezos, the founder of Amazon, is now the world's second richest person.
And exceedingly close to Bill Gates in wealth.
It seems an appropriate time then to look at how he runs his business - and what we can learn from it to help us run ours.
As an ambitious entrepreneur I know you are working extremely hard.
But are you thinking enough?
Sometimes we get so busy at work that we forget that taking time out to think can get us much better results.
