If you can dream it, you can do it.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
Begin to be now what you will be hereafter.
It's always too early to quit.
Be kind whenever possible. It is always possible.
The sum of the whole is plainly this: The nature of man considered in his single capacity, and with respect only to the present world, is adapted and leads him to attain the greatest happiness he can for himself in the present world.
