Keep It Moving

Let's say that something is said to be impossible but highly desirable.
Now let's say that we have one million people looking at the same problem. (1,000,000)
Ninety percent of these will determine that gaining a desirable outcome is impossible and will not even look at the problem. (100,000)
Ninety percent of these will look at the problem and determine that it is just not worth the time, resources and effort. (10,000)
Ninety percent of these will grow weary and give up. (1,000)
Ninety percent of these will not be prepared to deal the problem. (100)
Ninety percent of these will get close to solving the problem and settle for just being close. (10)
Ninety percent of these will become distracted by the rewards gained by just getting close and will turn their attention towards status and popularity. (1).

It is often said that one has to be one in a million to succeed.
But the trick is to focus on the goal and everyone else will simply fall away leaving only yourself.
Being the 'one in a million' is not that hard - just as long as you keep working towards your intended goal.
(And if you fail? Who hasn't? If you have never failed you probably aren't trying hard enough to be great. Just try again. You're probably only competing against yourself anyway.)
