It's always too early to quit.
Begin to be now what you will be hereafter.
If you can dream it, you can do it.
Always desire to learn something useful.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
Without feeling abashed by my ignorance, I confess that I am absolutely unable to say. In the absence of an appearance of learning, my answer has at least one merit, that of perfect sincerity.
