Absolutely, it all begins in the mind.
You cannot/will not achieve what your mind cannot believe or see. What to I mean by this? If you believe you're a failure, then you are and if you believe your a success, then you are! see what I mean!
Recently I've been learning and reading about various techniques from NLP, EFT, cosmic ordering and psychological reframing. I know some of you will say, psycho bable and it's all a waste of time. But I'd beg to differ, what if, you entertain the possiblilty that there is something in it. Then you begin to accept, that anything is possible. You start to create mental images of success in your mind, small things at first. Breakfast with a friend, getting tickets for a show, they happen. How about big things, running the Marathon and starting your own business. Then they happen. I'm not talking about wishful thinking, I'm talking inner belief, which creates actions, which create the truth, with create the reallity (I know because it happened to me).
I'm not saying it's easy, we all have a life time of emotional baggage to overcome, this creates a drag effect. But, slowly (even quickly) you begin the see and believe the truth. The world is what you see/make of it.
Check out the film "What the bleep do we know", watch with an open mind.
Live every day as if it we're your first, not your last,
