whether you believe it or not the type of energy you project is what you attract. If you are focusing on the possibility of not having enough you will keep getting that. Also the same if you are not confident in dealing with clients and etc you will not have control.
By not having control you will not have the confidence in your ability to deal with them in a professional manner. The same thing goes if you are selling products and basically any other thing. If you are not the type to believe in what you are selling who else will. Also you have to be proud of what you are selling.
Being proud of what you are, what you are doing and all that you do. Project the type of energy that you would like to receive in your life. The time that you spend on things that matter will not benefit you so redirect that to what you do want.
