If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
Never complain and never explain.
Things do not happen. Things are made to happen.
I can, therefore I am.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
The thing that's tricky is sometimes the best voices - just because someone hits the big notes and sounds amazing - it doesn't necessarily mean they make the greatest artists.
