'Don't sweat it too tough', 'You have tried', 'You just can't get that', and so on. These are opinions or thought that comes to mind when faced with Challenges.
The mere fact that you haven't attained your desire on a couple of attempts doesn't mean its beyond reach. Claiming what you desire is not a matter of chance, its a matter of choice, it is not a thing to sit wishing for it to be handed to you, it is a thing to be achieved. So reach for it!
You don't need to welcome or take in certain ideas or opinion because, True Power (that burning desire to achieve the impossible) is finding your own path and applying it with respect to achieving your goals.
Put in a little more effort than you think you possibly can!.
