And here are some quotes that are hopefully a wee bit motivational...

If there's no struggle, there's no progress (Frederick Douglass)

The more we do, the more we can do (William Hazlitt)

If you think you can or can't, you are right (Henry Ford)

If at first you do succeed - try to hide your astonishment (Harry F. Banks)

When you feel how depressingly slow you climb, it's well to remember that Things Take Time. (Piet Hein, "T.T.T")

For those who keep trying failure is temporary

Failure is the path of least resistance

You cannot have the success without the failures
And my favourite...
When things go wrong, as they sometimes will,
When the road you're trudging seems all up hill,
. . . When care is pressing you down a bit,
Rest, if you must - but don't you quit.
. . . Often the goal is nearer than
It seems to a faint and faltering man,
Often the struggler has given up
When he might have captured the victor's cup.
