If you continue to hold on to negative thoughts, all your action will be negative.
Whatever you want to receive out of life starts with a thought. Imagine that you want to be an Olympic swimmer, first will you will think, I want to learn how to swim and then, I want to learn how to swim faster. Once you have the thought you take action. Now if you had the thought, I want to be an Olympic swimmer, but I don't know how to swim so how can I make it happen, that is negative, so the action will be to take no action.
You have to believe in whatever you want, even if you cannot see a way of making it happen now. All you have to do is see it as fact in your thoughts and then take action. No one ever sat back after thinking I want to be a race car driver. They had the thought, took action and made it happen.
No one will believe in you more than you do, so it all starts with you. Once you make the decision as to what you want it is already yours. Only You can get in your own way of stopping it, and that is what so many people do. They listen to the nay-sayers, who tell them that they can't do it. By-pass the negative thinkers and show them that you can be and do anything you want. Life is for living and not for living in fear. Push past the fear and see you dreams come true.
