Try, Try Till you Succeed

It is in human nature to try once or twice and then give up. Like dialling a phone number...

But persistence is a virtue; woe to those who don't have it!

There is nothing that a calm mind cannot achieve. So, on failing, return to the easel and see where the new effort takes you. Sleep over it if you must, but wake with new vigour if you want to attain your goal.

For only the persistent one will win in the end. (The Hare and the Tortoise come to mind here, of course). Yes, you heard it all before. But come back to me if you've tried it and not succeeded - the point being, you probably haven't tried often enough...
