He is able who thinks he is able."
“No one can make you feel inferior without your consent.”
In order to be walked on, you have to be lying down."
To accomplish great things, we must not only act, but also dream; not only plan, but also believe."
Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great."
"Your Goals, minus your doubts, equals your reality'
'Success in any endeavor depends on which is a true expression of yourself'
Who do you think you are? Are you the problems you encountered yesterday, or are you the positive possibilities that exist today?
Are you the limitations that others have convinced you to adopt? Or are you the person who can work your way through whatever obstacles may confront you?
Are you the shortcomings and disappointments you've known? Or are you the most magnificent, most treasured dreams you can imagine?
Are you the empty, meaningless pursuits of the materialistic culture that surrounds you? Or are you the deeply held, lasting values you know to be truth?
Who you think you are can make all the difference, in this moment, in your life. Because who you think you are is who you constantly work to more fully become.
Who do you think you are? Choose right now to be the best you can imagine.
-- Ralph Marston
There are many perfectly logical and understandable reasons why you can't. Yet even so, you can.
There are difficult obstacles standing in your way, and you do not now know how you'll get beyond them. Yet even so, you can.
Others may persuade and convince you that you can't. Yet even so, you can.
If you can dream it, if you can imagine it, then you can be it, you can do it. If it is meaningful enough, and you commit the energy of your passion, you will.
Many of the things you now take for granted were once considered impossible. Many of the things now considered impossible you'll one day take for granted.
Go ahead and dream, go ahead and imagine, then get busy bringing those dreams to life. You can, if only you will
