Remember that 80% of the results will often come from 20% of the causes, so focus on finding the vital few inputs or actions that will provide the most benefit or effect.

The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few"). Other names for this principle are the 80/20 rule, the law of the vital few, or the principle of factor sparsity. Management consultant Joseph M. Juran developed the concept in the context of quality control and improvement after reading the works of Italian sociologist and economist Vilfredo Pareto, who wrote about the 80/20 connection while teaching at the University of Lausanne. In his first work, Cours d'économie politique, Pareto showed that approximately 80% of the land in the Kingdom of Italy was owned by 20% of the population.

Give honest and sincere appreciation. - Dale Carnegie

Lincoln once began a letter saying: "Everybody likes a compliment." William James said: "The deepest principle in human nature is the craving to be appreciated." He didn't speak, mind you, of the "wish" or the "desire" or the "longing" to be appreciated. He said the "craving" to be appreciated...Let's try to figure out the other person's good points. Then forget flattery. Give honest, sincere appreciation. Be "hearty in your [compliments] and lavish in your praise." and people will cherish your words and treasure them and repeat them over a lifetime - repeat them years after you have forgotten them.

Remember that you can influence your mind positively and change your life for the better by using the principle of autosuggestion.

Through the dominating thoughts which one permits to remain in the conscious mind, whether these thoughts be negative or positive is immaterial, the principle of autosuggestion voluntarily reaches the subconscious mind and influences it with these thoughts. Recall what has been said about the subconscious mind resembling a fertile garden spot, in which weeds will grow in abundance, if the seeds of more desirable crops are not sown therein. Autosuggestion is the agency of control through which an individual may voluntarily feed his subconscious mind on thoughts of a creative nature, or, by neglect, permit thoughts of a destructive nature to find their way into this rich garden of the mind.

Begin with the end of your task, goal, project, or dream in your mind by mentally envisioning and creating a picture of exactly what the end result will look like.

To begin with the end in mind means to start with a clear understanding of your destination. It means to know where you're going so that you better understand where you are now and so that the steps you take are always in the right direction. "Begin with the end in mind" is based on the principle that all things are created twice. There's a mental or first creation, and a physical or second creation to all things. Take the construction of a home, for example. You create it in every detail before you ever hammer the first nail into place. You try to get a very clear sense of what kind of house you want.
