If you think you can do it, you can.
The most effective way to do it, is to do it.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
The dog that trots about finds a bone.
Well done is better than well said.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
