I myself strictly follow these two principles for all work. At one stage of my life i developed a strong desire to teach. It is possible to get success from any business if you put in your best efforts. Moreover, a positive attitude is a valuable asset to your success. A negative attitude is extremely detrimental to your well being. We all have more or less positive and negative traits. Qualify for that amount of motivation to make dreams come true. I have no doubt that if you develop a positive attitude and continue your efforts, you will eventually overcome all obstacles and reach the door of success.
