If you believe something is possible, and your attitude is that you are willing to do whatever it takes for however long it takes to get the job done, then success is just a matter of time. You can increase your self belief by the books you read, the CDs you listen to, and the people you associate with. If you put good things in your mind, you will become stronger and you will believe more in yourself.
“Whether you think you can or think you can’t – you are right.”
– Henry Ford
