You never want to think you know all there is to know about your specialism.
You see, if you know everything, then there is nothing left to learn. Which means you will not get any better.
Learning more leads to improvement in all areas of your life.
This improvement enables you to achieve your wildest dreams.
Which is why if you think you know all there is to know, you cannot grow.
If you think you don’t know it all and are hungry to learn more, the world is your oyster.
